Hi, I have couple of questions regarding the permit_mynetworks option.
1- is the permit_mynetworks must be added to allow bounces emails from postfix? or postfix can still send bounces or undelivered email notifications without need to add permit_mynetworks in the smtpd_recipient_restrictions? 2- Is the permit_mynetworks must be added so the postfix can work properly handling the emails ? anyway our users uses sasl authenticate that's why we want to remove permit_mynetworks, but we are afraid that this might break some thing in postfix, that's why we want to be double sure. ? - Also our last question, In case of different case that the mail server is secondary mail server , it relays back the email to the primary server when it is back. 3- do we have to add permit_mynetworks in smtpd_recipient_restrictions? so the secondary server can send the emails to the primary server (when the primary server was down) ? or still the secondary server can send the pending emails to the primary server even if permit_mynetworks in not written in the smtpd_recipient_restrictions? Thanks Michael Peter
