MailScanner:: Sendmail

Check List and Issues

Previous Issues

MailScanner never scans emails.

On a new CentOS 6 server emails enter the queue /var/spool/mqueue.in corretly from the sendmail process.

I have confirmed that this process is the one started by MailScanner for receiving emails in to /var/spool/mqueue.in

Once an email is placed in the directory, straight away it is proccessed and delivred to the intended user.

Mailscanner never gets a chance to take this message and send it though all it's filtering.

Dovecot issues

Using a seconday server to feed webmail activities though via Horde, I ran in to a problem where I could login via Horde to Centos 5.x server but my first Centos 6.x server I could not.

On the Centos 6.x server I added the folloing line to /etc/dovecot/conf.d/10-mail.conf

And restarted dovecot.

All fine.
