For the record, I've discovered some more info about this.
The "DoVRFY" option does nothing for sure.
Adding the "real" MTA info to localDomains enables recipient
validation; i.e. it is enabled as soon as you add the
"=>mx.domain.com" information to localDomains, regardless of the
DoVRFY setting.
Recipient validation will NOT work if you use the asterisk wildcards
like "*domain.com=>mx.domain.com". This is because, at line 8856 of
the source, this expression: exists($DomainVRFYMTA{lc $2}) ends up
looking for "domain.com" without taking wildcards in to account.
So, I got it working. Hopefully this information comes in useful for others.
