- I had to manually create the virtual folder for all my users or they couldn't access their mail at all. Is this fixed in 2.0?
No.
OK, is it considered a bug that should be addressed? IMO there should at least be a way to tell dovecot to ignore the non-existence of a particular folder.
- My users were getting errors when accessing via POP3. The possible meaning of such a virtual folder under POP3 is lost on me, but I had to enable the virtual plugin for that protocol too. I think that should at least be in the documentation, or better yet the requirement should that it be enabled for POP3 should be dropped.
I think you could put the virtual namespace inside protocol imap {} section.
I'm pretty sure I tried that and it didn't work for some reason. Unfortunately I don't remember the reason, so I could be mistaken.
- I couldn't get the virtual "conversation view" inbox to show any messages. But maybe that's because of a possible issue I describe below with x-mailbox
- The "all" virtual mailbox would only show 89 messages. I switched it to be a mirror of my "archive" mailbox and the number started to look more reasonable. This could be the "lots of mailboxes" bug describe in http://dovecot.org/list/dovecot-news/2009-December/000145.html
"lots of mailboxes" should cause error to be logged.
What does the error look like? I could search my logs for it.
- I tried to create an IMAP search, rather than a virtual folder, that looked for x-mailbox INBOX header like the virtual folder does. It too came up empty. It doesn't exactly surprise me because I don't see an x-mailbox header in any of these messages.
x-mailbox doesn't use a header, it uses the actual mailbox name where the message exists.
Oh... what if the message exists in multiple mailboxes? Typically anything in INBOX can also be found in my "all mail" archive.
I guess that means it's crucial that, whatever else I do, INBOX should be part of the "all mail" virtual folder in order for this to work. I didn't quite understand that before, and I think it's important to have a description somewhere of how x-mailbox works that would help me to get to that conclusion. Certainly the existing description at http://wiki.dovecot.org/Plugins/Virtual that it represents the "original" mailbox isn't adequate for that purpose.
Lastly, I want to report that for me, the speed of these IMAP searches doesn't begin to approach what I can do with mairix if I want a message's entire thread. I'm happy to use mairix, although it would be nicer not to duplicate that capability if it's already in the server. But it needs to be fast. Is there something I can do to make it go faster?
How slow is it? How many messages do you have? I think it should be pretty fast.
150523 messages in 2.6G
Anyway, dovecot -n output and contents of dovecot-virtual file could help figuring out what your problem is.
Having got the x-mailbox insight (I think---thanks), I have tried the following combinations:
~/Maildir/virtual/INBOX/dovecot-virtual
INBOX zz_archive* inthread refs x-mailbox inbox
shows only messages in INBOX. THe archives are actually in folders like zz_archive.2010.01
~/Maildir/virtual/all/dovecot-virtual
INBOX zz_archive* all
~/Maildir/virtual/INBOX/dovecot-virtual
virtual.all inthread refs x-mailbox inbox
shows only messages in INBOX
~/Maildir/virtual/all/dovecot-virtual
- all
~/Maildir/virtual/INBOX/dovecot-virtual
virtual.all inthread refs x-mailbox inbox
Appears to hang
~/Maildir/virtual/INBOX/dovecot-virtual
INBOX zz_archive.*.* inthread refs x-mailbox inbox
Appears to hang. For example, the little pie chart in Apple Mail that shows mailbox scanning progress is stopped. Wanderlust gets totally stuck.
