I believe if you run `eximconfig` the script asks if you will be handlnig mail for more than one local domain. Otherwise, it is near the top of /etc/exim.conf:
"Specify your local domains as a colon-separated list here. If this option is not set (i.e. not mentioned in the configuration file), the qualify_recipient value is used as the only local domain. If you do not want to do any local deliveries, uncomment the following line, but do not supply any data for it. This sets local_domains to an empty string, which is not the same as not mentioning it at all. An empty string specifies that there are no local domains; not setting it at all causes the default value (the setting of qualify_recipient) to be used." For example, on my home machine: qualify_domain = ghettobox.dhs.org local_domains = localhost:ghettobox.dhs.org:colby.dhs.org:andross.dhs.org When I send out mail externally from my machine, it sends as [EMAIL PROTECTED] (unless I have the mailer configured otherwise). I am able to receive mail to any of the local_domains (other than maybe localhost) from the outside world. I have had quite a time configuring exim, while I find it more desirable than sendmail it is a little awkward after using sendmail for a while. You may want to check: http://www.exim.org While it is not necessarily expansive and all inclusive, it really helps on some things. As for perl scripts, I can't help you there. I did a google search on "perl parse mail header" and came up with some leads: http://www.perl.com/pub/doc/manual/html/pod/perlfaq9.html http://www.oreilly.com/catalog/prkunix/excerpt/PWPMch04.html http://www.infobiogen.fr/people/fred/doc/perl/script-pl-idx.html http://sunsite.org.uk/packages/mh/contrib/audit/ If anything, they may provide some examples (which has helped me learn quite a bit). -nicole > Hi, Anyone have experience setting up Exim as a single IP/multiple > host mailing system?
