Today it came to my attention, via
https://phabricator.wikimedia.org/T151229,
that Phabricator's inbound email has been failing silently for several days.
Since no error messages were being delivered it easily went unnoticed over
the weekend.
I just fixed the root cause, however, an unknown number of replies to
Phabricator tasks have gone into the void without being recorded on the
intended tasks.
If you regularly interact with phabricator via email, I would like to ask
you to check your sent-mail to be sure your comments made it into
phabricator. You will likely need to re-send any messages that occurred
since at least Friday the 18th.
I apologize for the inconvenience. As a user of Phabricator's built-in
notifications I never even notice the email functionality, and as a result,
it went untested for too long.
Regretfully,
