I've Installed Postfix with Dovecot on CentOS 7. Everything is working good when I try to send / recieve emails from services like Outlook.. etc.
However, there is a problem when I send an email from my account on Gmail to my email on my server. The messages never get to my server, instead, they are delivered back and that's the reason mentioned in the message:
Technical details of temporary failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain xxxxxxxx.com by xxxxxxxx.com. [xx.zz.186.133]. The error that the other server returned was: 454 4.7.0 TLS not available due to local problem
Here is my
main.cf file: http://pastebin.com/3Di4PYxt
Here are the files in the
access header_checks.inbound.db ldap transport canonical header_checks.internal main.cf transport.db generic header_checks.internal.db master.cf virtual header_checks header_checks.submission relocated header_checks.inbound header_checks.submission.db ssl
I have those files inside /etc/postfix/ssl:
server.crt server.csr server.key server.key.secure
I followed this tutorial to Install the mail server: http://www.krizna.com/centos/setup-mail-server-centos-7/
Note: I've seen this question and it didn't help.
