Hello ALUG, I mentioned this on #alug the other day, but I thought I'd just check to see if anyone else has any ideas regarding it - especially as I can go into more detail here. My mail setup on my server has broken. I'm using Exim's virtual host method to forward mail sent to the server to a couple of different places. In /etc/exim4/virtual I have files for the domains: /etc/exim4/virtual +- ariada.uea.ac.uk +- sara.uea.ac.uk +- studios.uea.ac.uk which contain rules like: admin : richard.lewis@uea.ac.uk * : :fail: Unknown recipient. Please direct general comments to comments@studios.uea.ac.uk I have the necessary config in 350_exim4-config_vdom_aliases and I have: domainlist local_domains = @:localhost:dsearch;/etc/exim4/virtual in 01_exim4-config_listmacrosdefs. I've configured Exim using dpkg-reconfigure exim4-config answering like this: 1) internet site; mail is sent and received directly using SMTP 2) System mail name: musariada.mus.uea.ac.uk 3) IP-addresses to listen on for incoming SMTP connections: 139.222.208.19 4) Other destinations for which mail is accepted: studios.uea.ac.uk; sara.uea.ac.uk; ariada.uea.ac.uk 5) Domains to relay mail for: none 6) Machines to relay mail for: none 7) Keep number of DNS-queries minimal: no 8) Delivery method for local mail: mbox format in /var/mail/ 9) Split configuration into small files? yes When I try to send mail to, e.g., events@studios.uea.ac.uk I get the following error in /var/log/exim4/mainlog 2007-10-08 10:07:54 no IP address found for host MAIN_RELAY_NETS (during SMTP connection from mailgate5.uea.ac.uk [139.222.130.185]) 2007-10-08 10:07:54 H=mailgate5.uea.ac.uk [139.222.130.185] F=<richardlewis@fastmail.co.uk> rejected RCPT <events@studios.uea.ac.uk>: Unrouteable address and I get an "undeliverable" message from the UEA mail server (see below). Does anyone know why my Exim is not forwarding mail correctly? I'm afraid I don't really understand email and consequently I don't know exactly what's wrong here. When a message is sent to, e.g., events@studios.uea.ac.uk, does it go to some uea.ac.uk server first (mailgate5.uea.ac.uk?) and then does this server attempt to begin an SMTP conversation with my server? If so, is my server engaging with it correctly? And why is my server rejecting mail? (/Is/ my server rejecting mail?) Is it because it can't forward it to richard.lewis@uea.ac.uk? If not, why not? When I first set this up (in June, I think) I'm sure it used to work. Someone on #alug suggested that sending mail to canonical domain names (which studios.uea.ac.uk is) is not a good idea? Could this be the problem? But if it is, why do I see evidence of a connection in my Exim log? Surely if it was not possible to send mail to CNAME domains, it wouldn't even begin a connection? Any information would be very much appreciated.
