SMTP with Google Apps not connecting

@mattryan29:

I checked in /etc/services and saw SSMTP available on that port…
/etc/services is a static list of official names for ports–not any indication of what's going on. You probably want:

netstat -l

You have Google Apps in the thread title, so I'm not sure why you're hitting your Linode. Can you elaborate on your setup?

My setup consists of Ubuntu 10.4, apache2, php, and mysql.

The application thats not working properly attempts to send mail via smtp. But the connection is never made.

netstat -l produces the following

Your netstat shows smtp and ssmtp so something's listening. What's your email server and does your /var/log/mail.log show anything useful.

Ok really crazy… it wouldn't work with opt code caching enabled. All good now.
