Problem setting up postfix
and gotten to the check your logs step. After sending the test email and checking the log, i see:
Jun 23 03:31:57 li115-209 postfix/pipe[9727]: 95FEAA6B0: to=<first@medetis.com>, relay=dovecot, delay=0.04, delays=0.03/0.01/0/0.01, dsn=4.3.0, status=deferred (temp
orary failure)
Jun 23 03:39:01 li115-209 postfix/qmgr[9710]: 95FEAA6B0: from=<root@li115-209.members.lineode.com>, size=455, nrcpt=1 (queue active)
Jun 23 03:39:01 li115-209 postfix/pipe[9755]: 95FEAA6B0: to=<first@medetis.com>, relay=dovecot, delay=424, delays=424/0.02/0/0.07, dsn=4.3.0, status=deferred (temporary failure)</first@medetis.com></root@li115-209.members.lineode.com></first@medetis.com>

check dovecot configs and mysql.
$ tail -50 /home/vmail/dovecot-deliver.log
li115-209.members.lineode.com does not resolve. In today's spam-filled world you can't expect a remote mail server to accept mail from an unresolvable source.
Your hostname should resolve to your IP
Your IP should reverse-resolve to your hostname.
Very time intensive, but I learned to be much more careful.
Not only do they maintain it, but it's their storage and their bandwidth, and their expertise in Spam Filtering, etc.
If you think setting up Postfix was a pain, good luck it keeping it running smoothly, without malware, or spam, or getting your IP blacklisted (none of that is rocket science, but it does take a lot of time, and it's a never ending process).
For small domains (under 50 user accounts) I haven't run a SMTP server in-house for years. Don't miss it (or the hassle) a bit.
