This was a weird one! Thanks for all the suggestions you guys offered - 
they were a great learning experience for me, and got me a lot more 
familiar with Horde.

In my servers.php file my "server" value was set to "localhost". This 
had been working fine up until the mail server had it's melt-down and 
kernel panic. After I rebooted the server I was getting some strange 
"permission denied" messages from sendmail in the mail log, and Imp 
logins stopped working. After a search of Google groups for similar 
problems, late yesterday I found someone else who had experienced the 
same problem with the sendmail "permission denied" messages. It turns 
out that when the server restarted, the loopback interface was not 
assigned an IP address!  The /etc/hosts file identified "localhost" as 
127.0.0.1, but there was no interface with that IP address assigned.

As soon as I assigned lo0 it's IP address the sendmail error messages 
stopped appearing and Imp logins started working again. Funny how much 
better things work when the loopback interface is fully configured :)
