[Dovecot] can't receive mail from other hosts

[Steve Strong]

ok, this makes total sense...

the logs show that postfix does not get the email to process.  So, i 
don't think it's postfix/main.cf -- at least it's configured just as 
redhat recommends to work with dovecot.  i just looked at the firewall 
settings and by adding all of these ports:
    25, 110, 143

i was able to get my mail client to quit reporting errors -- are there 
other ports that should be openned?

i also looked at dns, an MX record points to the server correctly and 
dig calls give the correct answers

i'm encouraged, but still stumped, any suggestions?

thanks
steve
