The cyrusv2 mailer won't work as-is because of the way Sendmail rewrites
addresses for local mailers.  I'm told by the Sendmail folks that 8.13
_might_ have a way of tweaking this.  Until then, try the following
(this documentation below was submitted to me a while ago, but I haven't
added it to CVS yet):

+ <h4>Configuring <a href="http://www.sendmail.org/">Sendmail</a></h4>
+ 
+ <p>In general, follow the instructions in the 
+       <a href="install-configure.html">configuration
documentation</a>.
+ Here are the only caveots we have found:</p>
+ 
+ <ul>
+ <li> It is easiest to use the mailertable to route mail to Cyrus,
rather than 
+ adding the domain to the local-host-names file ($w).  This prevents
Sendmail 
+ from changing the domain name to the local host name.
+ <pre><kbd>
+ example.com              cyrusv2:/var/imap/socket/lmtp
+ </kbd></pre></li>
+ 
+ <li> You'll have to use the Cyrus mailer in LMTP mode, and you'll have
to 
+ change the mailer flags so that it provides the full domain while 
+ communicating LMTP.  Specifically these changes:
+ 
+ <pre><kbd>
+                 S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP
+ </kbd></pre></li>
+ </ul>
+
