I also had that problem since most of the spam I was getting to my domain was to nonexistent users. I discovered sendmail has a local mailer flag that indicates whether sendmail should check the recipient against local users at smtp time. The flag is 'w'. My sendmail.mc has the following line: define(`CYRUSV2_MAILER_FLAGS', `A@/:|mw')dnl where cyrusv2.m4 has the line: _DEFIFNOT(`CYRUSV2_MAILER_FLAGS', `A@/:|m') This solved my problem but it requires that I have a local machine account for each cyrus user. As a small domain that's not a problem for me, but others might find it too restrictive.
