I think I have found what I need, I must increase the value of the parameter "transport_retry_time".
### transport_retry_time (default: 60s) The time between attempts by the Postfix queue manager to contact a malfunctioning message delivery transport. Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). The default time unit is s (seconds). I will increase the value and I will see how it behaves thanks to everyone for helping me, take good care Regards, El mié., 5 de ago. de 2020 a la(s) 10:57, SysAdmin EM (emaw...@gmail.com) escribió: > Is it possible to change the retransmission time to the second max? > > El mié., 5 de ago. de 2020 a la(s) 10:41, SysAdmin EM (emaw...@gmail.com) > escribió: > >> 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?
