<p><font size="3" face="Times New Roman"><span style="font-size:12.0pt">Depends on how you are defining "secure", here. I run Postfix and Dovecot and find that they work well together. If I had centralized authentication and Dovecot 2.0, I think I would be
very happy, but right now I have neither.<o:p></o:p></span></font></p>
<p><font size="3" face="Times New Roman"><span style="font-size:12.0pt">The big thing you want after checking that you're not spammer-friendly is to ensure that you do not generate backscatter. Backscatter is a form of spamming which relies on an MX to be unaware
of all valid recipients. Without that, the MX will store and forward literally everything, which will generate bounces when the primary MX received and rejects mail sent to an invalid user.<o:p></o:p></span></font></p>
<p><font size="3" face="Times New Roman"><span style="font-size:12.0pt">In short: make sure the mail systems are all using the same database and rejecting mail for non-existent users in the SMTP conversation, instead of later when a bounce is required.<o:p></o:p></span></font></p>
