<p>Greetings,</p>
<p>I'm trying to debug an issue with a user who is finding emails
(user uses Thunderbird as client) ending up in Junk folder, and
constantly marks email as Not Junk, but important email ends up in
Junk folder.</p>
<p>I have sieve set up, but am unable to determine if this is the
result of a sieve problem (sieve will automatically move certain
emails into Junk if certain headers are present, but these headers
are not present on these emails.)</p>
<p>I'm looking in Dovecot debug logs to try to figure this out, but
all I can find is sometimes this, and I don't know if this is
relevant. Can anyone point us in the right direction for solving
this issue?<br>
</p>
