Question: When installing @Mail the Exim SMTP server fails compiling with the error message:

What is the solution to the compile error?

Answer: The mysql-devel package is missing from your system ( the libmysqlclient library and mysql header files )

As a solution:

1: Download the mysql-devel package from the mysql.com website, and install for your system

2: Or install the mysql-devel/libmysqlclient package for your Linux distro.

The current policy of pop before send does not work very well. It only allows people to send email out an hour from the FIRST time they pop in. This can be fix tho with a simple change to the addrelay function in Log.pm.Change the following: (more...)

Question: I run the Plesk control-panel and use @Mail as a replacement email-server. However, at times when Plesk is updated or rebooted the Plesk mail-server starts, conflicting with @Mail. How do I fix?

Answer: Since the server-mode of @Mail has a custom copy of Exim, it needs to replace any existing mailservers.

If using Plesk or another mailserver first shutdown the other instance:

# killall -9 exim

Locate the binary for the Plesk Exim or other mailserver and:

chmod 000 /usr/sbin/exim

This will force the binary not to execute from any scripts/startup procedure.

Next, use the chattr command to "lock" the binary from been changed by any Plesk startup scripts:

chattr +i /usr/sbin/exim

Next, restart @Mail and the changes will be in effect, and the default Plesk mailserver will not conflict again.

/etc/init.d/atmailserver restart
