I suggest to create a dedicated "horde" account for messages created by horde
without any user interaction.


If you have access to the mail server you may try to enable  
verbose/debug logging
at the MTA.

then send a message as user and send a message via horde-alarm for example.
compare the smtp commands of both smtp sessions. Than you will know  
what's going wrong.

If I remember correctly, it's the SMTP HELO name used horde.

horde will talk a different protocol SMTP vs. LMTP. You need an LMTP-Server...
