Greetings! We switched from Exim 4.6.3 to postfix 2.3.3 as mail relay host on RHEL 5. We start getting report that email are rejected. We did a telnet emulation and found that postfix reject email header as below:
MAIL FROM: "My Company Support" <supp...@mycompany.com> If I simply change it to: MAIL FROM: "My Company Support" Or: MAIL FROM: <supp...@mycompany.com> The postfix will let it through. Not sure what configuration can be put in postfix main.cf. can someone shed some lights? Thanks, Steve
