Hi,

in some cases I receive emails with multiple recipients to a single 
domain, e.g. a@... and b@.... The first recipient 
a@... is not greylisted because the tripple is known from past 
emails. The second recipient is not known and runs into greylisting. 
This causes some servers to send the second try via another smtp from 
another class-C network which in this case was on a DNS blacklist and 
the mail was blocked. I already use "subnetmatch /24" so in most cases a 
second try from another smtp is running through. But is there a way to 
accept all recipients of an email if one tripple is know, e.g. accept 
b@... because a@... is known?

Ciao!
M.

I think that in a most general case - no, because triples not tuples are there for a reason: one's spam can be another's ham (e.g. per static rules, ldap or otherwise curl'ed preferences).

There is a lazy mode for auto-whiting just the remote sender (relay+domain iirc) which may be what you want here.
