Are the imap services only bound to localhost ?

As root,
netstat -anp | grep LISTEN

the command returns:

OK, I can telnet to the pop3 (11) and imap (143) ports OK.

I can use "openssl s_client -connect your_domain_name:pop3s" (995) and ...:imaps (993) properly. Both the SSL versions report a self-signed certificate.

I can see an SMTP server on port 25.

So all the services are listening and responding.

Post subject:  Cert
Yeah its just the self signed postfix cert. Im the only one who will have access to the email so not a big deal right now. But i still get the same s#!t with outlook and thunderbird. Am i a complete idiot? LOL ok you dont have to answer that question :)

tried to use disabled plaintext auth <-- that one means you need to enable secure authentication.

Post subject:  Update:
AS of now sending from the email account in outlook sends to any address so thats good. Sill no recieving in outlook.

Thru the shell sending to another one of my emails (different domain) does not come thru but it can recieve. Each is acting the opposite of the other........1 can send but not recieve the other can recieve but not send.

Just about to give up and use the US Postal System good ol fashion stamps.

This may seem like a silly question..have you looked at google apps? http://www.google.com/apps/intl/en/group/index.html

Post subject:  Final Step maybe?
Ok good news is using IMAP i can send and receive perfectly with ports 143 / 587.

So for now thats good enough for me. Not sure (...well thats obvious) why IMAP connects fine pop says not a chance loser get out of here! So as long as i can send and receive is the important thing for now.

Thanks for all your input. New to Linode and this was my first question so I appreciate your time and support.
