I have Dovecot 1.2.9 from Ubuntu repositories on my server. Now I installed Horde and it give me sometimes the error "Mailbox does not support mod-sequences".

This would happen if trying to do obtain MODSEQ on a mailbox that
has mod-sequences disabled. That error should be caught and not be
user-visible (I recall fixing something like that a while back, but
in any case that's a topic for the Horde/IMP lists, not here).

...

Well, I must say, that I didn't know these mod-sequences, but I can' know all...

Well, the question now is: how can I enable the support of the mod-sequences on the mailboxes of my Server?

You probably do have mod-sequences available in general. But for
whatever reason a particular mailbox doesn't support it. This can
be do to a variety of reasons (e.g read-only access to underlying
data storage).

Hi Michael,

thank you for your answer. Could you suggest me how can I find the problem? On my Server I have a directory /var/spool/mail/ (permission 775,
owner exim, group mail). Dovecot runs with user "dovecot" which is in group "mail". The Mailbox directories have permission 755 and are owner from user
"exim" and group "mail". In the directories there are a directory "Maildir" with the same
permissions and users, and in this directory the usual
maildir-structure.

Is somewhat false?
