Hi,
What can we check/tune if there are ~35K mails in the active queue (stress test is being performed) and a mail spends ~4m in the active queue? Example: 2022-10-13 07:54:05.823323+00:00 postfix/qmgr ... (queue active) (no log entries here) 2022-10-13 07:58:12.308448+00:00 postfix/smtp ... relay=relayserver.ip[relayserver.ip]:25, delay=247, delays=0.06/245/0.09/1 The relayhosts are accepting the emails, the emails aren't deferred, the OS seems fine on both our side an on the relay nodes. Thanks!
