Are you using the latest snapshot? This started happening after updating today, between the snapshots that advertise MP kernel build number #626 and #627 on amd64. > > It would help if you shared your config The _only_ thing related to the "stdin" account in my ~/.fdm.conf is a single line saying account "stdin" disabled stdin Mail is otherwise filtered and sorted _exactly_ like the messages that I fetch from remote IMAPS accounts in the same configuration. The smtpd configuration for local-to-local delivery looks like action "local" mbox alias <aliases> match from local for local action "local" I did not send this to the bugs list because I wasn't sure it was a base system bug, a bug in fdm, or the intended behaviour after the various recent updates to smtpd, or just something that I'm doing wrong. If it is indeed a bug, then I'll write a proper report to the bugs list. Regards, -- Andreas (Kusalananda) Kähäri SciLifeLab, NBIS, ICM Uppsala University, Sweden .
