I'm trying to use my newfound powers to figure out something that's
bothered me for a long time. In one of my accounts, new messages
delivered to the INBOX will, for a day or two after delivery, keep
showing up as new every time I sync the server. I discovered that the
message is actually being given a new UID somewhere along the line
(which is gmail <-> mbsync <-> dovecot <-> Gnus), so it keeps showing up
as a new message. After a day or two, it stops happening.
I have three accounts backed by gmail. This happens consistently on one
account, occasionally on another, and never on the third.
I'm posting some logs, which I hope will at least show where the problem
is. It starts with a -VV output for mbsync, showing the message getting
added as new. Then there's a second mbsync run, showing the same message
getting added again, under a new UID. Then there's the output of
recording Gnus talking to Dovecot.
I think I went through the process a couple of times between mbsync
runs, so the UID went from 9971 to 9974, but it's still the same
message, and the Gnus/Dovecot record should come directly after the
second mbsync run.
I hope this is enough to at least know where to look next...
Thanks,
Eric
