Yes, Horde doesn't care what the SMTP provider is so long as it works.

No issues.

We use Horde/IMP (and testing DIMP) to provide web mail to our low-end
users.  Horde is great stuff, works across browsers well, is stable, and
deals with every tortured mail message (including ones that wig out
either Thunderbird [not really very hard to do :(] or Outlook].  For
groupware we use OpenGroupware,  and Horde is very easy to integrate
into almost anything.

They set it up wrong.
