Hello all

I am new here but now as much new to linux servers

I am trying (for the past 3 days) to setup a mail server.
I dont even know where to start so you guyz are my last resort...
This is the tutorial I was following:
https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql
I followed it twice!!
My SSL is self-signed!
At first it was rejecting mail.
Now it recognizes the mail and users but I can not connect to the server with a mail client (TB).

Trying to troubleshoot this i went through:
https://www.linode.com/docs/email/postfix/troubleshooting-problems-with-postfix-dovecot-and-mysql/

I have tried and tried endlessly.....I am kinda tired of this but it has to be resolved.
Hopefully with communal help!

1. Telneting ports 993/995 fails - connection refused

2. My iptables

4. dovecot.log does not have anything although I set the same usr:grp syslog:adm - is that correct??
(Enabling Verbose Logs on Troubleshooting guide)

CAN ANYONE GUIDE ME THROUGH RESOLVING OR LOCATING THE PROBLEM???

THANK YOU!

TWO Whole hours before a bump - on a work day - bwahahahahaha.

Just kidding, give it more time, you're asking people (who usually have a very high hourly consulting rate) to help you for FREE, so let them help you when it's convenient for THEM, plus you've given almost ZERO useful details.

I must say...you do have a point there...bwahahahahahahaha.

What do you think is missing as far as details?

Configuration files? Probably would be nice to see some configuration files.

Maybe "netstat -ntlp" to see what's actually listening.

"ps aux" is great for finding out what's running, too...
