Again... creating/managing users is NOT an MTA function, so this question has nothing to do with sendmail vs postfix...
if you don't want to set up your MTA to accept mail for anybody@yourdomain.com (and this is an unattractive option nowadays, with all that spam)
Catchalls are a bad idea in general, regardless of the spam situation, as they break recipient validation for senders (they don't know that they typo'd the email address)...
then your MTA has to know what users to accept mail from. So yes, *in most cases* the MTA has to know about your user database as well.
Ummm... try again...
I didn't say it shouldn't KNOW about users - which, absolutely, should be a REQUIREMENT (except in certain very special cases) - I said it isn't its job to CREATE/MANAGE them...
