Hi,
by discussion on IRC channel is post details here.
I am using virtual plugin in dovecot 2.3.13 and i have porblems with
subsription to these virtual mailboxes. I can setup autosubscribe to
them and it works as expected. I can SUBSCRIBE to them, dovecot returns
OK and they are added in subscriptions file, but then they are not
shown in LSUB output. I can UNSUBSCRIBE from subscribed virtual
mailbox (dovecot returns OK), but it is not removed from subscriptions
file and remains there...
I bother with this for long time. I tried to setup mailboxes without
UTF-8 chars, but that doesn't matter nad currently problematic mailbox
has not any nonASCII char (Virtual.Dnes). I tried to define mailboxes
in parent namespace too, doesn't help, nor defining only Virtual in
parent namespace (with and without separator at end). Some evidence
follows.
The (my) subscriptions file (the Virtual.Dnes is at end):
---------------------------------------------------------
V 2
<snip>
Virtual Dnes
---------------------------------------------------------
IMAP LIST (only Virtual namespace), as shown by dovecot's imap command:
---------------------------------------------------------
* PREAUTH [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT
MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS

WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY

SPECIAL-USE QUOTA ACL RIGHTS=texk] Logged in as slavko at slavino.sk
<snip>
* LIST (\Noselect \HasChildren) "." Virtual
* LIST (\HasNoChildren) "." Virtual.Dnes
* LIST (\HasNoChildren) "." Virtual.D&APQ-le&AX4-it&AOk-
* LIST (\HasNoChildren) "." Virtual.Pr&AO0-lohy
* LIST (\Noselect \HasChildren) "." Verejn&AOk-
* LIST (\HasNoChildren \UnMarked) "." Verejn&AOk-.Novinky
. OK List completed (0.004 + 0.000 + 0.003 secs).
---------------------------------------------------------
One can see that there are three virtual mailboxes, the Virtual.Dnes,
the Virtual.Dôležité (encoded) and the Virtual.Prílohy (encoded too),
including Virtual namespace.
IMAP LSUB output (again only Virtual namespace):
---------------------------------------------------------
* PREAUTH [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT
MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS

<snip>
* LSUB () "." Virtual.D&APQ-le&AX4-it&AOk-
* LSUB () "." Virtual.Pr&AO0-lohy
a OK Lsub completed (0.001 + 0.000 secs).
---------------------------------------------------------
As one can see, there are only auto-subscribed Virtual mailboxes, the
Virtual.Dnes is missing, despite that it is in subscriptions file.
The doveconf -n output (can be wrapped):
