Problem with chrooted user, manage-sieve plugin, lmtp and Thunderbird manage sieve extension: wrong symbolic link to active script

[Lev Serebryakov]

 I'm not sure, is it dovecot-managesieve plugin or Thunderbird extension.

 I have virtual users which are "chrooted" to their Maildirs, like this:

user_query = SELECT '/usr/home/hosted/v-mail/%d/%n' AS chroot, \
        '/' AS home, 'maildir:~/' AS mail, email.uid AS uid, email.gid AS gid 
FROM \
        <snipped>

 It works perfectly.

 I'm using sieve and manage-sieve plugins for dovecot. `.dovecot.sieve` link is 
relative, like this:

v-mail@onlyone:~/serebryakov.spb.ru/lev # ls -l .dovecot.sieve
lrwxr-xr-x  1 root  v-mail  17 Feb  4 18:19 .dovecot.sieve -> sieve/TOTAL.sieve

 It works. But when I deactivate/activate script via Manage sieve extension in 
Thunderbird link becomes absolute (with respect to chroot):

v-mail@onlyone:~/serebryakov.spb.ru/lev # ls -l .dovecot.sieve
lrwxr-xr-x  1 root  v-mail  17 Feb  4 18:19 .dovecot.sieve -> /sieve/TOTAL.sieve

  and delivery agent (LMTP) start to complain:

v-mail@onlyone:~/serebryakov.spb.ru/lev # grep .dovecot.sieve 
/var/log/dovecot.log
Feb 04 18:18:42 lmtp(l...@serebryakov.spb.ru)<36054><iPQqEtJD/WHWjAAAlMIKZw>: 
Warning: sieve: file storage: Active sieve script symlink 
/usr/home/hosted/v-mail/serebryakov.spb.ru/lev/.dovecot.sieve is broken: Invalid/unknown 
path to storage (points to /sieve).

 I'm not sure, is it problem of manage-sieve plugin, lmtp sieve plugin or 
Thunderbird Sieve extension...
