One approach

step 1: make sure packages 'expect' and 'telnet' are installed step 2: read: man autoexpect and RFC 2821 ... see worked example for handing email to a remote server http://www.owlriver.com/tips/sendmail-tip/ http://www.owlriver.com/tips/trace-sendmail/ step 3: experiment to taste in talking the protocol. 'expect' and autoexpect makes it trivial to build a script that works

Personally, I'd use the default Centos install of sendmail because it's there, it's easy, and it works the way mail has been intended to work for decades. The default setup is to accept only from localhost, but send anywhere. If you want to relay through a known host, configure SMART_HOST in /etc/mail/sendmail.mc and restart the sendmail service. Then your scripts and other programs can simply run sendmail to queue/delivey instead of doing it themselves, and can deliver to local recipients as well as remote.

If you really don't want a mailer and are ok with failures or want to handle queuing and retries yourself, the epel repo has perl-Mail-Sender which is a fairly complete smtp send-only client. After installing use perldoc or 'man Mail::Sender' to see the documentation.

The enclosed script works for python 2.5 (it's an example.)

If you don't use the localhost sendmail, then you'll have to relay through another sendmail server - and good luck with that.

Maybe you can relay through a Google?
