Hi ! I'm the networking pepole. :-) The exim server is on DMZ, the tcp/ip ports needed to comunicate smtp are open. In fact we receive emails from many domains but not from some domains.
I didn't setup any firewall rules to stop establised connections to continue. I can double check this, but I'm quite shure. Moreover absolutely no special rule is on the firewall about the connections from/to the backup MX server, but from there the email are arriving with no problems. thnaks a lot for the help Francesco Pasqualini On Mon, Sep 1, 2008 at 6:18 PM, Chambers, Phil <[EMAIL PROTECTED]>wrote: > > > > Do you have an application-level firewall between the Internet and your > mail server?
