[Dovecot] 1.0 beta3 not preserving X-Keyword header?

[Reuben Pearse]

Hi Gregory,

I recently been testing Dovecot (the RPM version was 
1.0-0_4_stable20050221.rh9.at) on of our RedHat9 servers using Maildirs. I 
am experiencing problem with Thunderbird 1.0 and 1.5 with message headers 
getting mixed up (i.e. you click on the message header in the list pane 
and it displays the message body of the next email in the list). 

However when using Outlook Express (yes I have to admit I used it for 
testing!!) and Squirrelmail the messages are displayed correctly, which 
suggest it maybe a bug in Thunderbird. Interestingly I found a bugzilla 
report which looks like the same issue at:
https://bugzilla.mozilla.org/show_bug.cgi?id=209561

I am gonna try switching back to mbox on the server and see if this fixes 
the problem (although I'd really like Maildir to work as its so much 
faster)

[Dovecot] 1.0 beta3 not preserving X-Keyword header?






We've been putting 1.0 Beta 3 through the paces on our test system, and 
one 
of our users pointed out to me that Thunderbird's "labels" behave 
strangely 
on the new server.  In fact, there used to be a header added to the 
message 
via IMAP when Thunderbird placed a label on a message, but as of the 
switch 
from 0.99.11 to 1.0beta3, this label header is no longer placed in the 
message.

Specifically, Thunderbird adds the "X-Keyword: $LabelN" header when you 
add 
a label to the message in tbird, where "N" is [1-9].  This works on 
dovecot 
0.99.11 (RHEL4), but not on 1.0beta3.  1.0b3 doesn't seem to add this 
header 
at all, but rather seems to keep this information somewhere else.  Perhaps 

in the .imap indexes?

We're using mbox stores on the server.  This was tested with both 
Thunderbird 1.0.7 (most widely deployed) and Thunderbird 1.5.

Aditionally, we've found that if the .imap index directories are removed, 
all the Thunderbird labels on messages seem to get "confused", too.  I.e., 

if the user uses multiple machines throughout the day, changes in one 
client 
may not be reflected in another, when the user moves to a different 
system.

I'm still trying to get more details from the users, but have been doing 
preliminary testing that verifies this.  One of the users complaining 
about 
this is my manager, who makes extensive use of Thunderbird's "Label" 
feature, so he's a bit nervous. :\

Another thing we've noticed is the potential for bad behavior if a use 
switches from the old dovecot to the new dovecot, which seems to be 
resolved 
if the .imap indexes are removed...

Let me know what other information is needed, and I'll do my best to 
collect it.

Gregory
