How to relay all emails through FSMSC from postfix. There is no encryption on smtp. Incoming mails arives in F-Secure and in heder i see that they are scaned with F-Secure but when i try to send mail i have a problem. I've put the ip of FSMSC in relay_host and port 25 but messages are not comming to F-Secure. Am i missing something in setup? Should i configure outbound email in F-Secure or there is some problem with my postfix, or if u have some tutorial how to setup postfix and F-Secure Messaging Security Gateway to work togehter please let me know.
