I figured. I threw that idea in at the last minute, as I was writing. Is there anything I can throw into the signal handler to dig deeper, or do I need to look at either the system or Dovecot? It's strange that the "Broken pipe" occurs several times in succession, the message is ultimately delivered, but Exim still resends the message later. Is the transport legit? lmtp: driver = lmtp socket = /var/local/run/dovecot/lmtp batch_max = 32 Here are the relevant (AFAICT) log lines (sorry if the line-wrapping is problematic; blank lines are in the log): 2016-10-26 00:00:14 [7838] cwd=/ 3 args: /usr/local/sbin/exim -t -i 2016-10-26 00:00:17 [7838] 1bzIC6-00022Q-7J <= [email protected] U=root P=local S=366004 M8S=0 T="Logwatch for host.domain.tld (Linux)" from <[email protected]> for root 2016-10-26 00:00:17 [8060] cwd=/var/local/spool/exim 3 args: /usr/local/sbin/exim -Mc 1bzIC6-00022Q-7J 2016-10-26 00:00:17 [8063] 1bzIC6-00022Q-7J Failed writing transport results to pipe: Broken pipe 2016-10-26 00:00:17 [8063] 1bzIC6-00022Q-7J Failed writing transport results to pipe: Broken pipe 2016-10-26 00:00:17 [8063] 1bzIC6-00022Q-7J Failed writing transport results to pipe: Broken pipe 2016-10-26 00:22:32 [8117] cwd=/var/local/spool/exim 2 args: /usr/local/sbin/exim -q 2016-10-26 00:22:32 [8117] Start queue run: pid=8117 2016-10-26 00:22:32 [8119] 1bzIC6-00022Q-7J => user ([email protected]) <[email protected]> F=<[email protected]> P=<[email protected]> R=dovecot T=lmtp S=3727 2016-10-26 00:22:32 [8119] 1bzIC6-00022Q-7J Completed QT=22m18s 2016-10-26 00:22:32 [8117] End queue run: pid=8117 -- ## 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/
