I have some experiece both (Courier,Dovecot) with postfix. First off

Courier: relatively easy to configure and maintenance, gives an average
performance at mailbox access.
Dovecot: more complex configuriation (compared to Courier), g

Certainly. That does not warrant blindly stacking layers upon one another
simply because one can.
There are certainly layers that postscreen clearly renders

Hi,
I understand that postfix send bounces or failed delivered notifications
using empty sender.
But does postfix accept empty sender emails during the MAIL FROM command
during the SMTP conversation? because i think that postfix needs a valid
email address ?
