Viktor, My problem is that I cannot deliver the mail because the greylist does not allow it and in some cases I also receive the same error in the other MXs.
# Example Jul 31 09:30:08 smarthost03-ded postfix/smtp[22475]: A88B418003D5B: to=<ism...@ilaviola.com.ar>, relay=mx7.webfaction.com[185.20.49.162]:25, delay=969, delays=962/0.01/6.8/0.34, dsn=4.2.0, status=deferred (host mx7.webfaction.com[185.20.49.162] said: 450 4.2.0 <ism...@ilaviola.com.ar>: Recipient address rejected: Greylisted for 300 seconds (in reply to RCPT TO command)) Jul 31 09:31:04 smarthost03-ded postfix/smtp[22767]: A88B418003D5B: host mx9.webfaction.com[185.20.49.164] said: 450 4.2.0 <ism...@ilaviola.com.ar>: Recipient address rejected: Greylisted for 300 seconds (in reply to RCPT TO command) I am use PowerMTA and depending on the message I receive, I can perform an action such as hold the queue waiting for a certain time and not in postfix. I understand that postfix retries on all MXs in the domain, can I configure the retry time towards the second MX? I did not find it in the documentation http://www.postfix.org/qmgr.8.html Can i automatically send the queue into hold when i get a greylist error?
