Yes, I had to do something similar, on a smaller scale.
Assuming that you have your default mailer as cyrus, add something like
the following to your sendmail.m4 file, and rebuild your .cf. Replace
pop_mailer with whatever is apropriate. The two R lines need to go in
before the normal delivery to cyrus, otherwise these will never be
evaluated.
FI/etc/mail/pop-users
LOCAL_RULE_0
R$=I < @ $=w > $#pop_mailer $: $1
R$=I $#pop_mailer $: $1
Then list the user accounts in pop-users, one to a line.
For your number of uses, you will probably need to use a hash database
rather than a text file tho, but I'm not sure of the syntax off the top
of my head :-)
