Mailertable is the most common recomendation but it is not the only way.

Sendmail can check aliases for any mailer with F=A flag set.
The flag is set by default only for local mailer.

You can set the flag for another mailer using line as below in your *.mc
file:
MODIFY_MAILER_FLAGS(`CYRUSV2', `+A')

It is "techically possible" to make sendmail check cyrus mailox and
alias existence *before* sending reply to "RCPT TO:".

The solution below (so far) checks only for cyrus mailbox existence:
