Quoting Luca Bertoncello lucabert@lucabert.de:
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).
