[Dovecot] Dovecot Virtual Users with Sendmail

Tue Jan 1 01:52:48 EET 2013

Thank you very much for the article.  It was quite interesting.  All thirteen pages!  

Unless somebody else posts that they've managed to get Sendmail to work with Dovecot virtual users, then I think your suggestion to look at a different MTA might just be the best route to take.

Thank you again.  I do appreciate it.

I hope you have a happy new year!  -- All year long!!
