I hope I do not post sth that has already been requested but I found nothing similar in this forum.
I would find it useful to add an additional feature to this new whitelist feature of version 4.4. I would like to have the possibility to whitelist on base of the senders mailserverhost (not IP).
Otherwise I have no possibility to whitelist all servers of a provider because normally I do not know all their mailservers IPs (especially on bigger providers).
All reverse DNS entries of hotmail mailservers ends with *.hotmail.com (or *.bay0.hotmail.com?) .. whitelisting on base of that would be nice to avoid false positives of @hotmail.com mails.
Whitelisting of all *@hotmail.com adresses as it is possible right now is not useful because as everyone know a mailadress can be easily faked and spam is often sent with @hotmail.com adresses.
I know also reverse DNS entries can be faked.
Maybe someone has additional ideas for making this feature more proof.
I'm interested in your feedback.
