[horde] Horde webmail, FreeBSD, Imap or Smtp server outgoing authentication error virtual hosts

[David Mehler]

Hello,

I've tried asking this one on the imp mailing list and didn't hear
back. Is that list still active? I'm hoping someone can help me.

  I've got a new horde webmail install going on a FreeBSD 11.1 jail.
  I've got Dovecot set up so that it appends a domain name if one is not
  given, so that user and user at example.com can both log in. The Dovecot
 server handles imap authentication as well as smtp authentication from
 postfix. Dovecot in turn gets its authentication via a MySQL database.

  When I logged in with horde webmail I used for the first attempt
  username with no @example.com suffix. I logged in ok, but couldn't
  send an email, gave me a weird error no address associated with host.
  I logged out, logged back in using user at example.com the full address,
  and this time the message sending went through.

 I could provide Dovecot, Postfix, and/or Horde Webmail configurations,
 but didn't want to include them all without knowing where this issue
 most likely resided. If it matters the web server is Apache 2.4. I've
been told by the dovecot list that this is most likely a horde issue.

The url I've gone to is example.com/horde then I changed that in to a
virtual host thinking that might resolve the situation which made it
webmail2.example.com this didn't. That's with the vhost setting off
and on. These sites are all being served over ssl.

Finally, my goal eventually is to have two separate domains
example.com and example2.com both with it's own separate users, so I'm
hoping this has an easy fix.

 Thanks.
 Dave.
