Hi List Postfix 3.4.13 in use.
I'm observing a probably milter caused issue and wanted to know if there are ways to log the invocations of milter commands from postfix to the milter. As smtpd milter we use: MIMEDefang (using spamassassin / clamav) milter-greylist opendmarc Every now and then, an email to multiple recipients is constantly being rejected by Postfix with: milter-reject: RCPT from (sending server) 451 4.7.1 Service unavailable - try again later; With MIMEDefang I do now log every invocation of filter_recipient() which is invocated by the RCPT milter command. Observation: First handful of recipients show up in the MIMEDefang Log. Then there is a 30 seconds gap, then Postfix fails all remaining recipients and the complete email with 4.7.1 If one email triggers that issue, it is triggered every time, on all of our 3 MX with identical milter config. I start to suspect, that one of the other milter fails. Is there a way to log the milter commands sent from postfix to each milter from withing postfix to find out which milter is 'timing out' on RCPT?
