Fetchmail
When I run fetchmail, I get the error SMTP listener doesn't like recipient address xxx@localhost.
I'm currently using Exim with fetchmail and I'd like to use the RBL on Exim, but will it work? Do I need to configure fetchmail any particular way? As far as Exim knows, all mail is coming from 127.0.0.1. Will it check the source address against RBL? Or will it check the From: header?
