Not that I'd patronise blocking the postmaster address, but why do you
think that? The postmaster address is specifically for humans to contact
when something goes wrong. I'd really be not amused when some daemon
would start sending mail to my postmaster account.
The 'daemon' in question is often a 'zombie', and you probably
*are* being offered such traffic, but have easily blocked it
before it gets onboard, 'coz it has a bad odor about it in other
ways.
I'd far rather have those try to hit 'postmaster' than a gmail
(or other) off-box address, simply 'coz the various acl's
published here over many months and years have been found *very*
effective at 'early and cheap' blocking of bogus traffic.
- Whereas the alternative would require MUA filters that cannot
even make use of tools Exim has available at the earlier stages.
Note the OP's implied use of a dynamic local-part of the gmail
address in his example.
D'ruther use Exim's simpler, well-proven tools than re-invent
that particular wheel.
I don't get even one bogus message a month to 'postmaster',
though that may change if folks here elect to try the address I
posted.
