Rick, Assuming I read your email correctly and the IP address specified in the Peer List is an external IP and the true IP address of the destination server is an internal IP, this will not work. When IMail delivers a peered email, it is always to '[EMAIL PROTECTED]'. And, the IP address that IMail uses is the IP address specified in the Peer List on the originating server. So, since '[EMAIL PROTECTED]' is a foreign address to the destination server, it won't accept the message. In short, peering will not work when the destination server is behind a router/firewall running NAT.
Have a good one, Christian -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Rick Davidson Sent: Friday, February 28, 2003 1:46 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Imail Peer behind !&%$# MS ISA Server Yes, the primary domain name is specified in the alias box. I have the system config'd exactly like the three working peers, this is why I beleive it is an issue with the ISA server config Have a great day!
