First of all, I don't think this has set your CyrusV2 mailer as local. There is
a FEATURE for doing just that, if you must use it. Secondly, man, that path is
awfully long. I'm not saying that something will not work, just that it looks
ugly. Consider installing under custom paths. On Tru64 UNIX I use
"/usr/opt/Cyrus-IMAP-2.1.15" for program and config files and
"/var/opt/Cyrus-IMAP-2.1.15" for maildir, cyrus config and sockets. Just a

This definitely proves that "cyrusv2" is not local. "mailertable" is consulted
only for non-local domains/hostnames.

As expected - "example.com" is not local domain and the sender was not
explicitely allowed to relay, either by "/etc/mail/relay-domains" or Access

Proper course of action.

Sendmail is checking to see if "someone" is a local user of the system. Cyrus
has it's own "users" (rather mailboxes, than users) and they have nothing to do
with UNIX user accounts.
There are two paths you can follow.
LOCAL CYRUS DELIVERY
You can use a FEATURE, similar to FEATURE(`local_procmail') that refers to
Cyrus. Actually, there is a FEATURE(`local_lmtp', `/path/to/your/socket') which
should be what you want. If you still get errors, check if "w" flag was removed
from "local" mailer definition. You should have the option to define a class "N"
of user accounts that should be delivered using "real local" mailer, but I'm not
sure how it all works. I've never implemented this myself.
INDIRECT CYRUS DELIVERY
This is what I do:
- add domain "example.com" to /etc/mail/local-host-names
- add a virtual-user table entry: "someone at example.com someone at my.domain.com"
- add a virtual-user table entry: "someone at my.domain.com someone at IMAP"
- have/add an entry to mailer table: "IMAP cyrusv2:localhost"
Note that my solution will not work for virtual domains in Cyrus. It would be
best to follow the first trail.
