seems some spammers are using one of my personal domains as the from field in their emails, the local-part being random so I cant easily block it.
Block *all* addresses except those actually being used[1]... I had to do this years ago for a customer who has '@foo.com -> mailbox' when some moron spammed about 10e6 messages from <random>@foo.com and the bounces began to hurt. Dumping all but the few legitimate fed@foo.com, lucy@f00f.com or whatever worked pretty well and the load on the system dropped radically as things we stopping early in the SMTP conversation and thus the system wasn't actually having to try to deal with much state most of the time. --cw [1] You probably also want to make sure postmaster@ works (RFC requirement) and probably abuse@ (procmail/vacation auto-responder exclaiming your innocence)
