How do I stop emails going to junk/spam?

Here are the best ways to stop emails from being put in the junk mail folder. Add an SPF Record SPF - Sender Policy Framework records help reduce the chance of your domain being spoofed in spam messages. It can also increase the deliverability of e-mail to external providers such as Gmail and Outlook. You can add them individually by adding a TXT record to the domain with the data v=spf1 include:spf.stackmail.com a mx -all. This tells other providers that MegabitCloud Web Hosting is a confirmed sender of your domain's emails. Add a DKIM Record DKIM, like SPF, is a standard that enables a specific aspect of the email sending process to be authenticated. The premise of DKIM is to check that an email is really from the domain or sender that it said it was sent from and if it has been altered in any way in transit. You can add one by going to the hosting package for the domain and to the DomainKeys section. You then need to select the domain you wish to add on to and add a Selector. This can be any value or name you like. It’s simply a field to identify the DKIM record. Then select Add Signature. If your nameservers are with us we'll automatically add this as a TXT record for you. If your name servers are elsewhere you'll need to go to 'Options' for the newly created DKIM and copy the DNS Name and DNS Value to a TXT record with your current DNS provider. Edit the Junk Mail Filters If incoming emails are the issue then you can whitelist the mail in the Junk Mail Filters section of any hosting package. In the Junk Mail Filters section, you can set the general filtering level to tell us how strict we should be with incoming spam filtering. If you just want to allow a particular address this can be done by whitelisting it for a domain or the mailbox on the package. If you want to white list a single mail address then you would need to whitelist 'thataddress@thedomain.com' and if you want to whitelist a whole domain then you would want to whitelist '*@thedomain.com'. This will allow mail from the address/domain to bypass our spam filtering.

How do I add a DKIM record?

DKIM, like SPF, is a standard that enables a specific aspect of the email sending process to be authenticated. The premise of DKIM is to check that an email is really from the domain or sender that it said it was sent from and if it has been altered in any way in transit. Specifically, DKIM (DomainKeys Identified Mail), provides a foundation for distinguishing legitimate mail. A DKIM signature is placed in the header of emails sent by MegabitCloud | Web Hosting's mail servers so that the receiving mail server can then validate the signature using a public cryptographic key (2048 bit). It's added as a TXT record in the Manage DNS section for the domain name. DKIM does not outright mean all emails will be delivered. However, it does provide the receiving mail server with further information so it can make a more informed decision on the best way to handle the email. To add one at MegabitCloud  Web Hosting: - Head to your control panel account and go to Manage Hosting and 'Manage' the package you want to add a DKIM record. Or if you have one account, head directly to DomainKeys. - Select the DomainKeys icon. Firstly, we'll explainhow to add a simple DKIM record to your DNS. - Ensure you’ve selected the domain you want to add the DKIM record-to. - Add a ****Selector.****This can be any value or name you like. It’s simply a field to identify the DKIM record. Then select Add Signature. - If your nameservers are with MegabitCloud Web Hosting, we’ll automatically add the correct TXT record for you. - The signature will be added immediately to emails sent from the mailboxes under the domain selected. We will have automatically added a DNS record to ****Manage DNS.****You may wish to wait for this to resolve for DKIM to be effective. From here you’re all done: your emails will use DKIM as a method to authenticate email. You can also use the Advanced Options section. Selector – This is a unique identifier for the DKIM record and can be set to any value you like. For example, you could set it to indicate the name of an office location or the signing date (e.g. “october2019”). Granularity/Identity – By default, this is set to a wildcard value: '*'. You can use this field to set the DKIM record to be assigned to a specific mailbox, allowing you to constrain which mailbox can use this selector legitimately. For example, if you set the value of this field to be ‘sales’, only your sales@domain.com mailbox will use this DKIM signature. This field must match the local part of the signing address (mailbox). Note – This field does not form part of the DKIM record or signature and is simply there so you can record any information about this record for your own information. ****Service Type –****Currently, DKIM only supports signatures added to messages sent via ‘Email’ (i.e. SMTP). However, in the future, the DKIM standard may add more service types such as IM or VoIP, which we’ll then be able to support. This field can be left to either ‘*’ or ‘Email’ - changing this won’t influence behaviour at present. Canonicalization – Some mail servers and relay systems may modify an email in transit, potentially invalidating a DKIM signature. There are two options you can set: 'Simple' and 'Relaxed'. If you expect your email to be modified in any way, you should select Relaxedwhich is more forgiving to changes made the header and body of the email. Expiry Time – This is the time which, when elapsed, the DKIM signature will be invalidated in the mail header. By default, it’s set to 86400 seconds (1 day). You may wish to extend this if you believe deliverability of the email will take longer than 1 day. Flags - There are two flags available: 'Production' and 'Testing'. If you select Testing, you'll still receive a response to the email and the DKIM signature from the remote mail server, but the email won't be treated with different behaviour. Verifier systems may wish to track testing mode results to assist the signer. You'll mostly want to use Production.

Should you use POP3 or IMAP?

Both IMAP and POP3 are protocols that allow you to receive emails from a remote server. Your email client uses these protocol to connect to your mailbox server. You may have your email client on your smartphone, laptop and desktop, and this is where IMAP and POP3 have different uses. Post Office Protocol version 3 (POP3) downloads mail from the server and often deletes it from the server after it has done so. This means that depending on when your mail client checks for mail, you'll only receive the email on one device or mail client. This also means that when you delete an email from one device, it will not be deleted from another. For example, if you receive emails on your smartphone, deleting them won’t also delete them on your desktop mail client, so you will have an email that you have viewed appear as unread. Since POP3 downloads emails from the server and saves them in a local storage area, losing or damaging your local storage may cause you to lose all of your emails. Internet Message Access Protocol (IMAP) on the other hand, is suited for people who want to receive email on more than one device, which nowadays is most people who carry a smartphone. IMAP stores email on remote servers rather than downloading them to local storage, which is how the emails can be viewed on different devices. When you read, download or make any changes to emails on one device, it will synchronise across any other device using the same account. IMAP has the ability to only download the header of an email so it can be much quicker. We recommend you use IMAP. POP3 offers very few, if any benefits. When you are setting up your mail client, you will have the option to choose from IMAP or POP3. To set up either, you simply need to access your email account information through cpanel.yourdomain.com.

I’ve reached my mailbox quota size. What can I do?

With MegabitCloud Web Hosting all mailboxes have a certain limit on data storage. It's unlikely that you should ever fill this unless you're receiving a lot of spam, or have a lot of emails with large attachments. All the emails and attachments you have in your mailbox are stored on a server, and each mailbox is given a specified amount of space on the server. Once that space has been filled by email and data, you will no longer be able to receive emails. To check your mailbox usage: - Log in to cpanel.yourdomain.com and go to Email Accounts. - Locate your mailbox and the usage will be displayed next to it. To resolve this issue there a few options: ****Order a Mailbox Quota Addon.****You can increase the size of your mailbox in 10GB increments by ordering a Mailbox Quota Addon, available from the Mailbox Usage page. Empty your trash within your mail client. When you delete emails from your inbox they go into the trash folder which means they are still taking up space on the server. Make sure there are no emails that you may need from the trash folder because to clear them from the server will mean permanently deleting them. Usually, you can right-click on the trash folder on select an option such as 'Erase Deleted Items' or 'Empty Trash'. There are also settings in some mail clients that will automatically delete items when you send them to the trash, but if you accidentally delete an email it will be gone permanently. ****Clear your sent messages.****Similar to messages stored in the Trash folder, sent items will still remain on the server. Deleting your sent items will not mean they are deleted from the recipients' mailbox, just the mailbox they were sent from. You can either go into the Sent Items folder and choose which emails you wish to delete, or you can right-click and select “Delete”.

Why can’t I send emails?

There are a few very common reasons why you may not be able to send emails. Are your email settings are correct? Make sure the email account username and password that you enter in your email client are correct. The details you'll need to be using are found below: Account type: IMAP - Incoming mail server: imap.yourdomain.com - Outgoing mail server: smtp.yourdomain.com - Incoming server port (IMAP): 993 - Use the following type of encrypted connection: SSL - Outgoing server port (SMTP): 465 (or 587) - Use the following type of encrypted connection: TLS Are email sending limits being hit? Our mail platform has several limits in place in order to protect the reputation of the mail platform and prevent large quantities of spam emails being sent. Currently, our mail limits are as follows: Web servers: 500 emails a day. Mailboxes: 8000 emails a day. Message size/attachments: our webmail system accepts attachments up to 32MB in size, and the maximum message size in our network is 50MB. If any of these limits are breached, then it won't be possible to send mail from that hosting package or mailbox. In the case of the message size/attachment limit, you'll simply need to look at reducing the size of the email or the attachment being sent. Where do the MX records point? You can easily ensure MegabitCloud Web Hosting serves the emails by using the tool here: https://mxtoolbox.com/ If we host the emails then you'll see mx.stackmail.com returned. If anything else is returned you may wish to contact the provider to determine the cause of the issue. Is the mailbox disabled for suspicious activity? If you're receiving the following error when trying to send that the mailbox may have been disabled for sending suspicious emails. "SMTP: Error (550): Failed to add recipient “test@example.com” (Sending mail from this address has been disabled due to suspicious activity)." If you've received this error, please get in touch with our Support Team, they'll be able to get this resolved for you.

What are my email sending limits?

Email Account Limits The following limits apply to all messages sent via authenticated SMTP. This will primarily be used for email sent via a mail client, but can also include mail sent via your website if configured to send via SMTP. We impose a limit of 8,000 messages per e-mail address per 24 hours. The following limits also apply: - No more than 10,000 recipients per day. - No more than 2,000 unique recipients per day. - A single email may not be sent to more than 100 individual addresses. As an example, if you were to send 100 emails to 5 different e-mail addresses within a 24 hour period. We would count 100 messages, 500 total recipients and 5 unique recipients. Web Server Limits A limit of 500 messages per day is imposed on all e-mail sent by our web servers. E-mails sent by the web servers should be no larger than 5 MB in size. This applies to all messages sent via the PHP mail() function. Autoresponders An autoresponder only sends once every 8 hours per sender Zero Tolerance Spam Policy We take a zero-tolerance stance against the sending of unsolicited email, bulk emailing and spam. Please note: The distributed nature of our network means email can leave through different servers at different times. As a result, you may see periods when you can send a greater number of messages than the limits mentioned above. However, this behaviour should not be relied upon and is not supported. If you do wish to send a larger number of e-mails than any of the limits mentioned above, we would recommend looking at a specialist marketing email platforms such as SendGrid, Mailgun, or Mailjet. New Mailbox Limit When a new mailbox has been set up, the sending is limited to 50 per day for 7 days. This is actually an abuse rule to prevent new mailboxes from being set up and used immediately to send out high volumes of spam emails. To preserve the reputation of the platform and protect mail being sent from being spoofed as spam by third parties this rule was put place to protect that status.

How do I migrate emails?

To migrate your emails and mailboxes to MegabitCloud, you can use our in-house Email Migrations tool. This will let you migrate your IMAP mailboxes, your Gmail mailboxes and yourOutlook mailboxesinto MegabitCloud  Web Hosting. To do this: - Login to cpanel.yourdomain.com - Select which package you want to migrate emails into via Manage Hosting if you have multiple accounts, otherwise head directly to the Email migrations tool. - Select the Email Migrations tool that is within the emails section. - Enter the relevant credentials and then select Sync. - Hostname- This will be the hostname of the mailserver that you are syncing your emails from. If you're not sure what this is then it may be worth asking your previous hosting provider what this is. - Username- This will be the mailbox that you are syncing. - Password- This will be the password of the mailbox at your previous host and of the newly created mailbox at MegabitCloud Web Hosting control panel. Please note: you'll need to have set up the mailboxes within the MegabitCloud control panel first, using the same password as currently used by the mailbox. - If the sync fails to start, this is likely due to the credentials not being correct. You should confirm that the password you have used is correct and that the hostname is also correct before requesting support. Frequently Asked Questions Can I use the email migration tool more than once for the same mailbox? Yes, you can use it as many times as you want. You may want to do this if you've recently switched MX records so mail now routes to MegabitCloud | Web Hosting, to get the latest copy of the mail from the previous mail server you can simply redo a mailbox migration. This will then only migrate emails that are new, so you won't have any duplicate emails. Does the email migration tool move or copy emails across? The email migration tool copies the emails and folders across to MegabitCloud Web Hosting, so no emails are “removed” from your old mailserver/mailboxes. Can I only perform one mailbox migration at a time? Yes, you can only perform one mailbox migration at a time per package. Where can I find my hostname? Your previous host will be able to tell you your hostname. It is worth trying mail.yourDomain.com as that is a common hostname that is used.
