Horde uses a central call to the PEAR Mail package to send the  
messages, unless we have to send individual messages for all  
recipients, e.g. when sending encrypted messages. The result of this  
call is checked and any error is displayed to the user.
If you don't get an error, either the SMTP server didn't return one  
(and only logged it), or the Mail package didn't catch it properly.
