[horde] Question

[Mike Poznecki]

 I am trying to create a custom transport.  I have created the class in 
 a file that is located in php/Mail/Transport.  But when I try to select 
 it in the config page, I receive an error that says:
 
 "mySMTP" driver (for Horde_Mail_Transport not found). [on line 85 of 
 "/usr/share/pear/Horde/Core/Factory/Base.php"]
 
 What else must I do besides creating the file with my class and setting 
 up the conf.xml with the name of my class (minus the Horde_Mail_Transport) ?
 
 Is there something else I need to do in order for Horde to know about my 
 class?
 
 Thanks,
 Michael.
