I searched around for a while but can't quite seem to figure this configuration out.
I have my own FQDN that I use for my servers. My ISP also has a FQDN preassigned for my static IP (of the form IP-octets.isp.com). I want to configure Exim to accept mail that is addressed to user@mydomain and reject anything sent to user@ISP_FQDN. Everything I find online talks about rejecting sender hostnames when in this case I want to reject one of the two recipient hostnames. This is mainly for spam control. Right now it's not critical because most of the sending systems are performing a HELO without an FQDN but I've seen a few attempting to send to my system by using the ISP's global naming convention. I just want to kill that ability ahead of time before it gets abused. In my config file, local_domains is configured only for my personal FQDN, I don't have the ISP FQDN listed. I'm thinking that should already reject anything addressed to user@ISP_FQDN but I want to be sure. Thanks. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
