Straight from the Wiki:

Can IMP be used with SMTP authentication?

Horde and IMP can support SMTP authentication, but only if the SMTP  
server take the same authentication credentials as the POP/IMAP server  
(which would generally be the case) or the same set of credentials for  
ever user. Simply edit the Horde configuration as per the comments in  
the Mailer tab of the setup interface.

So far (Horde-5.0.4 and earlier) this has worked fine. If you enter  
'username' and 'password', these will be used for all users, if you  
leave them blank, the credentials used for logging in will be used.

But as I wrote before, this will still work in IMP-6.1.0beta, but this  
now requires setting up the 'smtp' array in  
'imp/config/backends.local.php'. I asked on the mailinglist if this  
was the new/preferred way of doing this, but Jan replied the above  
method should still work and this was a bug. Therefor I submitted this  
report. Feel free to close this bug report if you think otherwise,  
since what I intend to do still works, but requires now a different  
way of configuring it.

The above makes zero sense to me. Why would anyone bother to setup  
authentication on a SMTP server, but not require it for relaying mail?
