For many years I have avoided getting involved with Sendmail on my simple Centos 5 server that is used mainly testing php code (I use a php mail library). However I am now testing a CMS program (Concrete5) that uses the Apache mail service, and on my server the default is Sendmail.
The /var/log/maillog file contains these lines that are way over my head:

Is this something I can fix/configure with my limited knowledge?

Trying to understand Sendmail's errors
Re: Trying to understand Sendmail's errors
The destination server is rejecting your e-mail (stat=Service unavailable). It might be a problem at the destination server but if you know it's working it's probably rejecting your mail because you sent it with @localhost.localdomain sender.
