Cannot send email Postfix / Dovecot

[techlists at phpcoderusa.com]

Hi,

I was able to get my home server to work for the most part.  I think I 
need to make a few more adjustments.

I have Postfix and Dovecot configured and I can send email but not 
receive.  Nothing in the mail logs.

I am trying to connect using Thunderbird.

Config:

IMAP port 993 / ssl/TLS / Normal Password / username : 
keith at keiththewebguy.com and password that is in 
/etc/dovecot/dovecot-users

SMTP port 25 / STARTTLS / Normal Password / username : 
keith at keiththewebguy.com and password that is in 
/etc/dovecot/dovecot-users

Any thoughts on how to troubleshoot this?

Thanks!!
