Instead you would put the domain name(s) you wish to relay for (and I put both the domains (in the form ".mailserver.domain.com" with the leading dot) *and* lines with their IPs in /etc/hosts.allow - is this OK? > which are local to your server) in /etc/mail/local-host-names (previously called sendmail.cw). It's just me, myself, and localhost here ... but this begs the question: When I do the command `host my_ip_here` there aren't any lines that say hostname.domain.com mail is handled (pri=10) by ... So is it possible to even *get* mail delivered to my dynamic IP, for example, addressed to root@my.ip.here? > If you have a local network e.g. 192.168.0/24 and the access.db feature of sendmail is enabled you might add the following to /etc/mail/access: > 192.168.0 RELAY Does the above (scary, technical stuff) override any other files? > To answer your original question, relay-domains usually specifies domains you wish to relay for but aren't necessarily local to your server. You generally don't want to be an open relay so this file may be of little use in your case. /etc/hosts.allow controls who may or may not *connect* to your SMTP service. It may be useful for any IPs you specifically want to deny access to your service but it's not a good way to control mail routing. Hehe, "*generally* don't want to be an open relay?!"
