smtp_tls_security_level: verify versus secure
I do not understand the difference between verify and secure. If I assign the same value to smtp_tls_verify_cert_match and smtp_tls_secure_cert_match therefore not using the defualt values, is there still a difference between verify and secure or are they doing the same? Michael

5.5.4 Unsupported option:
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" If I simply change it to: MAIL FROM: "My Company Support" Or: MAIL FROM: The postfix will let it through. Not sure what configuration can be put in postfix main.cf. can someone shed some lights? Thanks, Steve

You can fix SMTP syntax with the smtpd_command_filter feature: /etc/postfix/main.cf: smtpd_command_filter = pcre:/etc/postfix/command_filter /etc/postfix/command_filter: /^MAIL FROM:\s*"[^"]+"\s+(<.+)/$1 But basically the sending app is badly broken.

We did a telnet emulation and found that postfix reject email header as below: MAIL FROM: "My Company Support" Are you sure that is indeed what is being sent? As Mr Venema (the author of Postfix) pointed out, this is not valid syntax. You might want to temporarily set notify_classes = resource, software, protocol, policy (and make sure you have an alias for the postmaster) to help track down this problem... re: http://www.postfix.org/BASIC_CONFIGURATION_README.html#notify Good luck!
