sSMTP Unable to send message using external mail server SMTP
I'm trying to finish up my Nagios install by having it email me. It was emailing me using /bin/mail so it always got sent to my spam folders. I installed sSMTP to try to send a request to my work's email server to be able to send out a message from an authenticated user.
Here is my /etc/ssmtp/ssmtp.conf file:
mailhub=10.200.120.148:25
UseTLS=NO
AuthUser= [email protected]
AuthPass=PASSWORD
So far I've been using the following command, and it will still arrive to my email inbox as root@localhost which causes it to go to my spam folder (with the exception of one email provider I have).
cat message |ssmtp [email protected]
I've looked at a few examples online, and they all seem to have pretty much the same as me. Does anybody see the any mistakes that I'm making?
Just to clarify, [email protected] is a user on the mail server that my work uses.
I'd start with sending a message while running tcpdump -A port 25 and watching the SMTP conversation.
If the remote mail system says the message is queued then sSMTP is working fine, and you'll have to look at the remote mail server. If it doesn't say it's queued, then try to fix whatever it says is wrong.
If you don't see any connections, only then is the problem is with sSMTP.
