Are you using develop?  My guess is that Horde_Mime_Mail is not yet  
fully converted to use the new Horde_Mime and Horde_Mail frameworks.

I try my best to keep it updated, and I ensure it passes all unit  
tests, but I don't actively use Horde_Mime_Mail ever so I won't  
personally catch any issues.  My advice would be to try to isolate the  
issue in a unit test and I could more easily debug.
