This is the way I do it:

"ev.co.yu" is our domain and is registered as a local-host-names entry,
VirtUserMap: Nikola.Milutinovic at ev.co.yu -> nikola.milutinovic at IMAP
MailerTab: IMAP:    cyrusv2d:localhost

Now two things are worth mentioning. Firstly, "IMAP" is NOT in the 
"local-host-names" - as far as I know, for a local domain Sendmail will 
not consult mailertable, as it will not consult virtual users table for 
non-local domain. Secondly, the "host part" for cyrusv2d mailer in 
mailertable has no usage. The definition of that mailer has actually no 
use for the $h macro. That can probably be changed, but I'd like Andrzej 
Filip (anfi) to do it, since he is the author of that definition.

What should be the best usage for the host part, since we could be 
requesting this change from Andrzej? I imagine it could be used for 
specifying which LMTP socket to connect to, but it can be elaborate, 
remeber Sendmail can connect to a local UNIX socket, just as easily as 
it can connect to a remote LMTP network socket. So, something like this 
would be nice, I just don't know if it is feasable:

cyrusv2d:unix:/var/opt/Cyrus-IMAP4-2.2.10/socket/lmtp
cyrusv2d:net:imap4.ev.co.yu

Nix.
