Hi, I'm using postscreen on a mailserver. Unfortunately, this does not work with some bigger mail providers, since they send the mail from a random host in their mail-server-cluster, so postscreen sees a new IP for each retry, and so sometimes never accepts the mail. Is there a way around this? Is it possible to e.g. match against x.x.x.x/24 instead of the exact IP? Thanks Roland
