As others have suggested - used a "port remapper" utility to take incoming connections on Port 26 (or some other port) and remap to Port 25 for IMail to see it as "normal traffic".
I suspect, though, that if your co-lo center is being so anal about Port 25 fixup, they probably have Port 26 and most other non-essential ports blocked. The only solution in that case is to use Port 80. Since Port 80 is the HTTP/Web port, it will ALWAYS be open in just about everyone's firewall. Of course, this means you probably need a dedicated machine or at least one that is NOT running a web server since Port 80 has to be free on your system in order to use a port mapper and redirect it to port 25. Best suggestion, of course, is to dump the co-lo and go somewhere else. It really is strange as the nature of co-lo is to provide ONLY "power, ping, and pipe" -- unadulturated bandwidth with "buyer beware" as far as security etc. Now, "managed services" usually includes firewall or other extra services - but these are purely on an "as needed" (or more likely, as paid for!) basis and can be chosen by the customer. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Paul Chan Sent: Wednesday, October 17, 2001 11:33 AM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Shared firewall and SMTP authentication Couple of issues with my co-lo: 1. The fixup protocol that is running is Cisco's way of helping to avoid hacking through certain ports (there are about 8 ports they have built the fixup protocol for). It is programmed to know what commands are valid for the port and will disallow commands that are invalid or will cause problems. It does not help with spam or anything like that but will help with buffer overflows or other types of hacks. 2. I'm on a shared firewall. If I have this fixup protocol stopped, that would effect everyone, something they don't want to do. I'm unfamiliar with firewalls and these protocols, so I sorta have to take their word.
