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. Here below is a snippet from master.cf of another instance where I use a Perl script for randomizing the smtp client to be used for outbound email: ------------------------------- MASTER.CF----------------------------- 127.0.0.1:21025 inet n n n - 0 spawn user=nobody argv=/etc/postfix/random-block1.pl smtp2 unix - - n - - smtp -o syslog_name=postfix-smtp2 -o smtp_helo_name=mx2.dominio1.it -o smtp_bind_address=xxx.xxx.xxx.111 smtp3 unix - - n - - smtp -o syslog_name=postfix-smtp3 -o smtp_helo_name=mx3. dominio1.it -o smtp_bind_address= xxx.xxx.xxx.112 smtp1 unix - - n - - smtp -o syslog_name=postfix-smtp5 -o smtp_helo_name=mx5. dominio1.it -o smtp_bind_address= xxx.xxx.xxx.113 veryslow unix - - n - - smtp -o smtp_fallback_relay= slow unix - - n - - smtp -o smtp_fallback_relay= ------------------------------- END MASTER.CF----------------------------- Here is the transport file used in my configuration: ------------------------------------ TRANSPORT ------------------------- testdom.it slow: testdom.com veryslow: trydom.it slow: trydom.com slow: ------------------------------------ END TRANSPORT ------------------------- Well: with the configuration files above, how can I update veryslow and slow transports for each IPs? What smtp_bind_address I have to set for slow/veryslow? Uhmm... I hope to have been clear.
