[Dovecot] No localhost after reboot

[Bob Hall]

I've been SIGHUPing Dovecot when I make changes in dovecot.conf. This 
seemed to work fine; I made changes to the imap_listen setting and 
Dovecot accepted them. However, I just reset
	imap_listen = *
and used killall instead of SIGHUP, and restarted, and Dovecot is 
listening on localhost. Previously, Dovecot would listen on both the 
LAN interface and localhost if I set
	imap_listen = <server name>:143
but now it listens only on the specified socket. 

The reboot that changed Dovecot's behavior also changed my LDAP 
server. It was using CRYPT as the default without the --with-crypt flag. 
But after the reboot, I had to recompile OpenLADP with the --with-crypt 
flag. (The flag isn't mentioned in the instructions on the OpenLDAP 
site.)

Maybe I shouldn't have swapped keyboards during the reboot. Or maybe 
the keyboard uses the wrong brand of pixie dust. Or maybe I need to 
hit it with a hammer. Or maybe the power company flushed out some 
fat electrons when they cleaned the tap brushes on the dynamos...
