[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.

No, it should work the exact same way with beta3, and it does work
with me.

This also sounds like there's something else wrong. Almost as if
Dovecot treats the mboxes as read-only and never writes the X-UID
etc. headers into them either?

1.0beta doesn't even notice the old indexes, so deleting them
shouldn't have any effect.

Odd... Maybe I have a setting wrong?

No, X-UID headers are definitely getting written in, and the Status header is being updated, too. It's allowing moves and deletes and expunges like normal. Just things like X-Keywords aren't being added when a client requests it.
The config file I'm using is:
protocols = imaps ssl_cert_file = /usr/share/ssl/certs/csefast.ucsd.edu_cert.pem ssl_key_file = /usr/share/ssl/private/csefast.ucsd.edu_key.pem login_greeting = Dovecot ready. max_mail_processes = 2048 verbose_proctitle = yes verbose_ssl = yes first_valid_uid = 100 mail_debug = yes default_mail_env = mbox:~/:INBOX=/var/mail/%u mail_full_filesystem_access = yes mbox_write_locks = dotlock fcntl protocol imap { ssl_listen = *:997 login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = session=yes dovecot } userdb passwd { } user = root }
1.0beta doesn't even notice the old indexes, so deleting them shouldn't have any effect.
Ah, okay, that actually makes me feel better. :)

No, they are enabled always.

Are the $Labels listed in X-IMAP or X-IMAPbase header in the first mail?
Try this manually:
MAIL=~/mail /usr/local/libexec/dovecot/imap x select mailbox x store 1 +flags test x fetch 1 flags x logout
Does the "test" keyword get added to mbox either?

Well, there is an X-IMAPbase header in the first message, but it does not seem to change when I diddle with Thunderbird's labels.
So, before I did anything, with thunderbird closed:
gruizade@csefast(pts/0):~ 49 > echo $MAIL
/var/spool/mail/gruizade
gruizade@csefast(pts/0):~ 50 > cp $MAIL inbox.backup
/var/spool/mail/gruizade' ->inbox.backup'
gruizade@csefast(pts/0):~ 51 > diff inbox.backup $MAIL
That diff verified that my copy is the same as my inbox.
Then I opened thunderbird, and applied $Label1 through $Label5 to the first five messages, respectively. I then told Thunderbird to compact all folders, and then quit. Then I tried to see what changed:
gruizade@csefast(pts/0):~ 52 > diff inbox.backup $MAIL
Diff told me, sadly, that nothing changed in my inbox. Thunderbird, though, seems to think the messages are still tagged, which leads me to believe the tagging is somehow cached either in Thunderbird, or somewhere else. I have no idea where that somewhere else would be, though, because Thunderbird on _another_ machine will pick up the labels, but no idea from where!
Both before and after I applied the labels, my X-IMAPbase header looked like:
X-IMAPbase: 1129222811 0000045702 $NotJunk JunkRecorded NonJunk $Label3 Junk $Label1 $Label2 $Label4 $Label5
It only seems to change when messages are added or removed from the inbox, and the only part that changes is the second number (last UID?) As messages are read, Status and X-UID headers are added/updated properly, though.
Try this manually:
MAIL=~/mail /usr/local/libexec/dovecot/imap x select mailbox x store 1 +flags test x fetch 1 flags x logout
Does the "test" keyword get added to mbox either?
Here's the session:
gruizade@csefast(pts/8):~ 25 > setenv MAIL ~/inbox.backup;

Looking in the mailbox after this test, there is indeed an X-Keywords header:
X-Keywords: test
Yet, no matter which Thunderbird I try to use, on which platform, this doesn't happen.
So, I'm really confused now.

Have you figured this out yet or have the later betas fixed it? The above command doesn't make Dovecot use all of its settings. Perhaps those had something to do with it. So instead of running imap directly, does the same happen also with:
telnet localhost 143 x login user ..and the rest of the commands..
I'm guessing maybe it has/had something to do with mbox_lazy_writes setting.

Actually, we were in a serious time crunch, and reverted back to UW-
IMAPd. After the next couple of projects get back under the belt, I
think I'm going to try to get dovecot running again on a test system
and see if I run into the same issues.
I'll let you guys know when I do this if the issue's resolved with
whatever the latest code is when I get to test this.

Try setting the mail_max_keyword_length option in dovecot.conf:
# Maximum allowed length for mail keyword name. It's only forced when trying # to create new keywords. mail_max_keyword_length = 50

That doesn't seem to affect the behavior at all.

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)
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 -- Gregory K.

Please use 1.0beta3 instead. Lots of bugs have been fixed since 1.0-stables, including this one.

Maildir isn't necessarily faster. In fact I think it's slower for most common uses. It's more reliable though.
