[SOLVED] PMG Postfix configuration

[Grogory]

Helo, I want to reject recipients after the DATA command, to prevent spammers from checking the presence of a valid smtp address at the rcpt to dialogue stage, before the date section, according to the recommendation of postfix:
http://www.postfix.org/postconf.5.html#smtp_address_verify_target
Is it possible?

I don't see why this should not work - but have not tried it myself - so definitely keep an eye on your logs to verify everything works.

Quite many things in SMTP do rely on the correct time of a reject code (the recipient verification of postfix itself needs a 5xx after the RCPT command to work for example

if you want to still try it - you need to modify the postfix config using the templateing system:

I hope this helps!

P.S. the 'TUTORIAL' tag of threads is meant to indicate if someone has posted a tutorial - i.e. a HOWTO - not a question
