upstart-file-bridge does not notice maildir delivery

[Tv]

Hi. It seems that upstart "start on FILE=/path/to/maildir/new/" does not detect email delivery to that maildir. I've also tried globbing with .../new/*

Maildir delivery is done by creating a file in tmp/, link(2)ing it to new/, and then removing the temp file. The delivery agent in this case is postfix, but the same behavior can be triggered with touch tmp/foo && ln tmp/foo new/foo

inotifywait reports a CREATE event on new/ when this is done.

strace'ing upstart-file-bridge shows that it sees an event, and stats the /path/to/maildir/new/unique.file.postfix path, but does not send an event to upstart.

Hi Tv - thanks for reporting. I believe this is the same issue as reported on bug 1221466.
