I got remote mail server that for some reason don't accept connections from my IP this way: # nc mx.poczta.onet.pl 25 220-mx.poczta.onet.pl ESMTP 521 5.7.1 Service unavailable; client [5.9.116.9] blocked using postscreenbl.opbl.onet.pl.
Which is fine but my exim drops email from queue silently, no delivery attempt is logged and bounce is not generated which obviously is terrible. 2021-04-01 01:54:45 1lRkfc-0001w9-TQ <= test@xxxxxxxx H=(xxxxxxxx) [127.0.0.1]:53112 I=[127.0.0.1]:587 P=esmtpa A=fixed_plain:test@xxxxxxxxx S=1159 id=c90e9f920c38d302dfe2e213ab7b9cbc@xxxxxxxxxx T="test" from <test@xxxxxxxxx> for sdfadbvzxcb...@poczta.onet.pl 2021-04-01 01:54:45 cwd=/var/spool/exim 3 args: /usr/exim/bin/exim -Mc 1lRkfc-0001w9-TQ . -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
