Seems you haven't searched the archives..
https://lists.horde.org/archives/horde/Week-of-Mon-20130805/048873.html
Or perhaps

Whilst it's more likely to be the first one, you should also not rule out
the second.

Also, it took a while on the dovecot and postfix lists to get you to
provide Version numbers for the software you're seeking help on.  Would be
great if you could do that here too.  No one cares that you're running
Ubuntu, or what version.

You have provided 0 information about the version of horde or imp; whether
you have a user backend, or authenticate with IMAP.

You're also not installing horde in a manner recommended by the devs, (not
that I am one) thus your request for assistance would be directed to the
Ubuntu package maintainer.

Cheers.
