Topic: How can disable TLS in postfix?

Hi, I install Iredmail 0.8.0 on Debian 6.0.5. I changed etc/dovecon/dovecon.conf  and POP3 is work without ssl,
but in  postfix etc/postfix/main.cf  I can't disable TLS. I change smtpd_use_tls = no
smtp_use_tls = no, but it doesn't work. How can i do it?

Re: How can disable TLS in postfix?

May i know why you want to disable TLS in Postfix? You can perform smtp auth without TLS with default setting.

If you REALLY want to disable TLS in Postfix, please set/update below setting in main.cf:

smtpd_tls_security_level = none

Reference: http://www.postfix.org/postconf.5.html# … rity_level

It's recommended to use POP3S/IMAPS/SMTPS (submission) for better security.
