[horde] smtp host for misc POP3 'change_server'

[Justin Zachor]

> 5. Again, mail never arrived at either of those remote accounts


Ok, what's happening is that even though I'm logged into IMP as 
justinz at mojo.net, IMP is telling SMTP that the message is from 
justinz at fluffy.homeip.net . This FROM is not allowed because the 
account doesn't exist (even though it IS a local domain);  Also, I
bet Mercury32 wouldn't accept it anyway because even though the 
connection is local (127.0.0.1), the correct FROM (justinz at mojo.net)
is not. Doh!

I also gotta figure out what I did to IMP config to make it
do this....
