- Linux Kernel: Linux 2.6.32-504.16.2.el6.i686 on i686
- RAM: 6GB
- OS: CentOS 6.6
- Postfix 2.6.6
- Dovecot 2.0.9

So here is the issue: I have been trying to setup my Postfix/Dovecot and at one time I had email going out (pre-Dovecot) and then I installed Dovecot and email stopped working (but I can connect to Dovecot through email app). I have searched all over the internet and followed many different How-To's.
So here is the error log message:
May 27 12:53:17 HOST dovecot: imap-login: Login: user=USERACCOUNT, method=PLAIN, rip=EXTERNALIP, lip=INTERNALIP, mpid=24257, TLS
May 27 12:56:18 HOST postfix/smtp[24155]: 34AF0120A1C: to=RECEPIENTEMAIL, relay=127.0.0.1[127.0.0.1]:2525, delay=41158, delays=40858/0.06/300/0, dsn=4.4.2, status=deferred (conversation with 127.0.0.1[127.0.0.1] timed out while receiving the initial server greeting)
- I have replaced the host name with HOST, the external ip with EXTERNALIP, the internal IP with INTERNALIP, and the recepient email with RECEPIENTEMAIL

I'm at wits end! Someone please help me!
Ideal scenario: I want to run my postfix server to serve mail to my domain users. All email will be routed to smtp.verizon.net through port 465. In coming mail would be delivered directly to my postfix server. Users will be able to use Outlook or other email clients to connect to the server and read/send mail. I will also be installing Roundcube or SquirrelMail to have a webmail for them to use. All email and login should go through SSL/TLS (using self-signed certs - no commercial certs yet though this may change at a later time).
Thank you in advance for your help.
