I don't understand Postfix internals so deeply, but I see another possible problem. Please correct me if I'm wrong!
Basically, you want to run separate instances of Postfix in separate processes, right? These instances (if not configured carefully) probably put their queue files in the same directory (/var/spool/postfix by Debian default). Isn't it possible that there is a race condition between multiple instances, and an e-mail queued by one instance actually gets delivered by another instance (thus another IP)? If you've taken care of this, or it is not a problem for Postfix, or in case I said something very stupid, I'm sorry. 2015-03-24 11:29 GMT+01:00 <i...@itrezero.it>: > > Dear Mr. Dukhovni, > you're right, I'm not a great expert of Postfix but I'm here to learn! > In fact, you're last answer is the solution of my problem: > > > Sure looks like you don't understand that each instance of an > > smtp(8) transport needs all the relevant settings specified. > > There's no "inheritance" between "smtp" and "slow" for example. > > I just updated my master.cf, and ALL IS FINALLY CORRECT: > -------------------------------------- MASTER.CF > ----------------------------------- > xxx.xxx.xxx.79:smtp inet n - n - 10 smtpd > smtp unix - - n - - smtp > -o syslog_name=postfix-smtp79 > -o smtp_helo_name=mx4.domain.it > -o myhostname= mx4.domain.it > -o smtp_bind_address= xxx.xxx.xxx.79 > veryslow unix - - n - - smtp > -o smtp_fallback_relay= > -o syslog_name=postfix- smtp79 > -o smtp_helo_name= mx4.domain.it > -o myhostname= mx4.domain.it > -o smtp_bind_address= xxx.xxx.xxx.79 > slow unix - - n - - smtp > -o smtp_fallback_relay= > -o syslog_name=postfix- smtp79 > -o smtp_helo_name= mx4.domain.it > -o myhostname= mx4.domain.it > -o smtp_bind_address= xxx.xxx.xxx.79 > -------------------------------------- END MASTER.CF > ----------------------------------- > I thought that was ineritance between smtp and other transports settings > (slow, veryslow, etc.) :-( > THANK YOU A LOT! > > > > > > However I've another question.
