LinuxQuestions.org - Postfix error: private/smtp No such file or directory

Good afternoon and happy new year!

I'm in the process of moving to a new server and am running Ubuntu 11.10. It looks like dovecot was upgraded to 2.0, which is a major revision to what was there before (1.something).

In the process, it looks like my old config files no longer work so I'm down to starting from scratch. I'm racking my brain with an issue. I can receive mail fine but cannot send mail out:

Code:

Dec 27 08:43:17 helo postfix/anvil[21959]: statistics: max connection rate 1/60s for (smtp:117.201.49.196) at Dec 27 08:39:55

Dec 27 08:43:47 helo postfix/qmgr[56377]: warning: connect to transport private/smtp: No such file or directory

Dec 27 08:43:47 helo postfix/error[36098]: 400B263200CC: to=<someaddress@gmail.com>, relay=none, delay=315493, delays=315493/0.01/0/0.02, dsn=4.3.0, status=deferred (mail transport unavailable)

Now, upon inspection, it looks like the socket to the smtp service does not exist on /var/spool/postfix/private

How do I create this? I've set up dovecot to create the SASL authentication correctly (at least I think so) since I can log into the server. Mail within the system seems fine (outside the fact that spamassassin is logging it as spam, but that's a whole other issue).
