Update
Jeremy, I saw your post via web. I do not even use check_data, it is commented. In the check_rcpt I now added a condition-less "accept" VERY early to mitigate effects of later rules. Problem persists.
And NOW:2019-10-18T13:56:03.718183+02:00 mailfass exim[4587]: SMTP data timeout (message abandoned) on connection from hummus.csx.cam.ac.uk [131.111.8.88] F=<[email protected]>
Perhaps someone from your side may have look ;-)Few MTAs still get their messages through. I was successful via telnet and did not see anything odd.
################# Hi all, all of a sudden (after a reboot of the machine, but I cannot see a connection to that) exim produces a lot ofdata timeout on (message abandoned) on connection from mx.example.com [IP] F=<[email protected]>
in my logs. These are always the same systems, that retry and fail again. Other systems don't show probs. By the looks this happens in the rcpt or data ACL, as the F= is available in the log.
I reinstalled last week's exim.conf to cancel recent changes, but this did not help.
Hope your answers come through ;-) Will follow on the Web archive. Yours urgently Hardy
