This is the BIG PICTURE, not a detailed recipe: On Imail 1. SMTP:syslog server, enter ip of IMGate 2. POP3:log to syslog On IMgate: 1. Install syslog-ng, and modify syslog-ng.conf to write 2. Install pop-before-smtp PERL script for postfix, adapted to Imail POP3D, etc. 3. stop the syslogd of the OS. 4. start syslog-ng and pop-before-smtp. On your edge router, block access from internet to IMgate port 514. In DNS, add an A record: smtp.somedomain.com. A ip.of.imgate Tell your users to change their mail client programs to send outgoing mail to smtp.somedomain.com, port 25. They can have SMTP AUTH required or not in their mail programs, IMGate will not announce SMTP AUTH anyway. BONUS: if you have roaming users having difficulty with their access provider blocking port 25, set IMGate also to listen on port 10025. And have your users send the outbound mail to server smtp.somedomain.com:10025 >Once this is set up >then we have to go through the painful process of explaining to all of our >users how to change thier SMPT settings to the IMGate. no, just point their mail client�s "smtp server" to smtp.somedomain.com, which itself resolves to ip of IMGate. >Also anyone know how >much overhead this might add to a box.. right now IMGate is just on a P166 >with a small HD assembly... adding all of the stress of a Spool... what kind >of impact do you guys see. we have about 300 domains and an avg of 10-15 >users per You probably won't notice it. syslog is UDP, short packets. One more log file is used on IMGate, and it adds a new, short line only for every successful POP3 login on Imail.
