[Manish]

Hello,

If you face issue with emails getting stucked in mail queue on cpanel server and receive error "All deliveries are handled by MailScanner" when you run mail queue manually then there is issue with the MailScanner installed on the server.

Following steps will fix the Mailscanner issue and can be run in SSH at any time without harm:

   
• /scripts/buildeximconf
• service exim restart
• /usr/mscpanel/mscheck.pl

When you run above commands on the server result should be as below.

[root@~]# /scripts/buildeximconf
Configuration file passes test!  New configuration file was installed.
/etc/exim.pl.local installed!
