Hello Timo,
thanks for your swift response!
* Timo Sirainen <[EMAIL PROTECTED]> [08-10-25 20:22]:
I couldn't reproduce this, but this should fix it anyway:
http://hg.dovecot.org/dovecot-1.2/rev/0738739a8152
[...]
Fixed: ttp://hg.dovecot.org/dovecot-1.2/rev/ba6ec21af651
Thanks! I was just looking at the repository, while you were committing
these fixes ;) But these fixes uncovered another bug. I can SELECT now,
but FETCH fails:

On an unrelated note, given the above configuration file, using a
dovecot-virtual file like
| mbox/*
| all
causes dovecot to complain:
Oct 20 13:56:59 vertikal EXT(lars): : Connection closed bytes=22/350
Oct 20 13:57:03 vertikal EXT(lars): :
/home/lars/Mailbox/virtual/test/dovecot-virtual: No mailboxes defined
Fixed: http://hg.dovecot.org/dovecot-1.2/rev/3f6fa7862843
Thanks. This works now, with a minor glitch. The directory backing the
"mbox" namespace looks like this:
Archiv/list1
Archiv/list2
foo1
foo2
As "Archiv" is a directory, it is not selectable (of course). Using the
above dovecot-virtual file, I get "NO Mailbox isn't selectable: Archiv"
if I try to select the virtual mbox.
This message does not occur, if use "*" instead of "mbox/*" as mailbox
pattern.
BTW: I really like dovecot's easy-to-reach debugging facilities.
- Lars.
