[WBEL-users] Email troubles connecting to mail fromremoteworkstation

[decampbell1]

Ok... in both ipop3 and imap,  disable = no
I turned the firewall off (service iptables stop) and there was no change..
I tried both regular pop3 and ssl.
My iptables do not appear to be blocking specific ports but I am blocking 
various ip address ranges from Europe, Asia, etc. (I do this regularly when 
I see attempts at scanning my server...
The following is from my mail log files.

Jan 23 18:51:22 mail ipop3d[7422]: AUTHENTICATE LOGIN failure 
host=c-xxx-xxx-xxx-xxx.client.comcast.net [xxx.xxx.xxx.xxx]


I do believe that sendmail is not the problem but I could and usually am 
wrong...
but, I can send emails to the server and it correctly receives them in the 
various accounts...
I can log in locally to the server and read them..
 also the server can reply to them and I do receive those replies at the 
various email address.. (hotmail, yahoo.. comcast.net etc.)
I have researched the docs that I can find and have also purchased the Red 
Hat Fedora Linux 2 Bible ( which very loosely matches this OS)
