I very much appreciate your detailed steps on the changes you made and where to look.
This being my first real jump into more advanced configs and changes (coming from sendmail and squirrelmail). The "if it ain't broke, don't fix it" mindset.
Once I get into disecting postfix and how things like spamassassin, clamav, roundcube, and such interact, I will be more comfortable with manual changes to necessary files.
Still in the "not even sure what the question is" mode at this time.
