With a recent move to a new data center, the domain for our system emails have changed. We used automated emails with our daily process for informational and report sending.
I edited the /etc/mail/sendmail.cf file where it had an entry pointing to the old mail server so I change this to our new one. This is how it looked:
#DSsmtp:smtprelay.<old>.org
DSsmtp:xxxsmtp@<new>.org
But this didnt solve our problem, when I testing the mail command we are still not getting emails.
Can you guys suggest where else I can look and make changes? Thanks.
