Sendmail aliases and Cyrus

[Anthony Tibbs]

Hi everyone,

I was trying to check the list archives for some hints, but it seems that 
that server is having some 'difficulties' at the moment, and isn't 
responding.

I am currently in the process of setting up another Cyrus/IMAP server, as 
I've been (personally) running Cyrus/Sendmail for a few years now with good 
results.  I had the usual sendmail+virtdomains+cyrus hoops to jump through, 
but now have THAT working all right (by way of a mailertable entries, i.e.

mydomain.ca    cyrusv2d:/var/lib/imap/socket/lmtp

The problem is that for this to WORK, mydomain.ca must not be considered a 
"local domain" (i.e. it must not be in local-host-names), since this results 
in a rewrite that strips the 'host' portion of the address off, and then 
Cyrus rejects the message with an 'unknown mailbox' error.

And all of this ultimately means that I can't use sendmail "aliases" (for 
non-local addresses), which I need in order to redirect such things as 
postmaster, root, etc. to a particular user.

Have I missed something simple here?  I've tried following the instructions 
at http://asg.web.cmu.edu/cyrus/download/imapd/install-virtdomains.html but 
that is where I am getting stuck...
