Issue :

How can emails going out from a particular domain be copied to a common email address ?

Solution :

In order to set up a forwarder for outgoing emails from a particular domain to another email address, use the following steps :

First, open the file /etc/cpanel_exim_system_filter using any of your favorite editors.

Add the following content to it :

if (
$received_protocol is “local” or
$received_protocol is “esmtpa” or
$received_protocol is “smtp”
) and (
$header_from contains “@domainname.com” )
then
unseen deliver username@domainname.com
endif

Now, if you DO NOT want to forward outgoing emails from a particular email address on that domain, you can add the following code in the /etc/cpanel_exim_system_filter file :

if (
$received_protocol is “local” or
$received_protocol is “esmtpa” or
$received_protocol is “smtp”
) and (
$sender_address is not ” username_escape@domainname.com
and (
$header_from contains “@domainname.com” )
then
unseen deliver username@domainname.com
endif

Finally, you should replace the values of the variables used in the above codes.

domainname.com – the actual domain
username@domainname.com – email address to which you want to forward.
username_escape@domainname.com – email address that you don’t want to forward

Save and exit the file.

Restart Exim using any of the the following commands :

/scripts/restartsrv_exim or

/etc/init.d/exim restart or

service exim restart

Issue :

It seems that by default, it is set to reject mails with a spam score of more than 20 at SMTP time. How to change the value of spam score for rejecting the mails at SMTP time ?

Solution :

You can do that by doing the following :

1. Go to WHM >> Main >> Service Configuration >> Exim Configuration Editor
2. Look for the section ‘ACL Options’ .
3. The first parameter under that deals with the spam score setting at SMTP time. De-select the check box corresponding to that.
4. When you de-select the check box, it will give you the other available options. Check the box corresponding to the desired value.
5. Click on ‘Save’ at the bottom to save the settings.

Issue :

Whenever a new account is created, the server sends out an email notification. Where can this setting be accessed and modified?

Fix :

Just go to WHM >> Basic cPanel/WHM Setup >> Server Contact Email Address.
You can make the required changes there.

Issue :

How to block emails from a specific address on a cPanel/WHM server using Exim ?

Solution :

This is fairly easy to achieve with Exim.
First you’ll need to find the system filter file for Exim. This can be found out through WHM >> Main >> Service Configuration >> Exim Configuration Editor.
Towards the middle of the page, under the section ‘Filters’ , you ‘ll find the path to the file.
Open that file via SSH using your favorite editor and add the following to it :

if first_delivery
and ( (“$h_from:” contains “emailtoblock@domainname.com”)
)
then fail
endif

If you would like a copy of the email to be sent to you after the message fails, use the following code :

if first_delivery
and ( (“$h_from:” contains “emailtoblock@domainname.com”)
)
then
unseen deliver “youremail@yourdomainname.com”
fail
endif

Make sure that you substitute the correct email addresses in the above code.

Issue :

How can the overall size of an email including attachment, encoding etc. be limited to a pre-defined value?

Solution :

This can be done in the following way :
Go to WHM >> Main >> Service Configuration >> Exim Configuration Editor
In the first box where you can type ( right below where you see ‘#!!# cPanel Exim 4 Config’ ), add the following directive :

message_size_limit = 100M

This will limit the overall size of the message to 100Mb

Issue :

Where can I check the current version of Horde webmail client running with cPanel ?

Solution :

If you have ‘root’ SSH access to the server then, simply open the file /var/cpanel/horde/version using your favorite editor and you’ll be able to see the current Horde version.

Issue :

How can a particular email account be ‘disabled’ temporarily. Note that the email account should not be ‘deleted’ ? Is this possible at all via cPanel?

Solution :

There is no direct functionality in cPanel at the moment for this. This feature might be added at a later stage.
However, you can achieve this functionality by modifying a few entries via SSH.

Comment out the entries related to the particular email account in the following locations:
/home/user/etc/domainname/passwd
/home/user/etc/domainname/shadow
/home/user/etc/domainname/quota

Make sure that you just comment them and NOT delete them as you might need them back later.

Issue :

How to allow sending of unlimited emails from the server?

Solution :

Just go to WHM >> Tweak settings >> The maximum each domain can send out per hour (0 is unlimited) >> Put ’0′ there and save the setting.

That should be it

Issue :

How can mails to root@hostname.com be redirected to another email address?

Solution :

If you have ‘root’ access to the server then open the file /etc/aliases in your favorite editor.
Look for the section “# Person who should get root’s mail” and make the change as required.

Issue :

No email accounts have been created on the domain but still the mail folder is taking up huge space.

Solution :

When a cPanel account is created, a default email account with the cPanel username is also created automatically.
In this case it seems that it has been set as catchall which is why any email sent to the domain at anything@yourdomain.com is saved under the default email address. You can delete them via Webmail .
(cPanel >> Email Accounts >> At the bottom, you will see the cPanel username and a Webmail icon besides it. Login to it using your cPanel password and delete the emails.)

To disable catchall and prevent this from happening again, do the following :

1. Login to the cPanel of the domain.
2. Click on ‘Mail’ icon.
3. Click on ‘Default Address’.
4. Click on ‘Set Default Address’ link.
5. Enter :fail: in the text box and click on ‘Change’ button.

This should fix the problem!

Issue :

Account was renamed from abc.com to xyz.com. After renaming, when trying to delete an old email address ( test@abc.com), following error occurs :

“The e-mail account test@abc.com was successfully deleted.
Sorry, you do not have access to the domain abc.com”

Fix :

Check the file /home/user/.cpanel/email_accounts.yaml and remove any entries pertaining to the old domain. This should fix the issue!

If you are using SpamAssassin then you need to update the rules now. There is a bug in the rules which will cause emails with a date of 2010 to be scored as spam. Here is an excerpt from the SA website :

===============================

Versions of the FH_DATE_PAST_20XX rule released with versions of Apache SpamAssassin 3.2.0 thru 3.2.5 will trigger on most mail with a Date header that includes the year 2010 or later. The rule will add a score of up to 3.6 towards the spam classification of all email. You should take corrective action immediately; there are two easy ways to correct the problem:

VP, Apache SpamAssassin

===============================

If you do not want to update, a quick manual fix is to just edit your 72_active.cf and change:

header FH_DATE_PAST_20XX Date =~ /20[1-9][0-9]/ [if-unset: 2006]

to:

header FH_DATE_PAST_20XX Date =~ /20[2-9][0-9]/ [if-unset: 2006]

Restart spamd and/or any other service that uses SA directly.

Issue :

The domain is hosted on the local server. However, the mails are controlled by an external server. The mailing lists is not working properly as it gets redirected to the local server instead of the remote mail server.

Solution :

This happens when there is a mismatch in the mail man settings. By default, the webpage URL in mailman would be pointing to the domain on the local server whereas in this case mails are being controlled by an external server.
To get around this, open the concerned mailing list located in /usr/local/cpanel/3rdparty/mailman/lists/.
Get into the config.pck file. Search for the domain name (webpage URL) and replace it with the remote server name/IP.

This should resolve the issue.

Issue :

An erstwhile regular account was migrated to be a parked domain on another account.
How can the email messages be restored to the parked domain?
P.S. Backup of the original account is available.

Solution :

Following assumptions have been made in this case :
Parked domain : abc.com
New account : xyz.com ( Username=xyz)

1. Re-create all the email accounts after parking the domain abc.com on xyz.com.
2. There would be a folder named ‘abc.com’ under the new account at the following path :

/home/xyz/mail/

Replace that folder with the corresponding folder available in the original backup.
