earthlink and email authentication...

(1/2) > >>

charlottezweb:
Howdy guys...hopin someone here uses Earthlink as their ISP and also has external pop email.  I just spent 30 minutes with their less than helpful support and he didn't understand how email systems work.

Basically, and it's been a year or so since I've had to deal with this, but Earthlink requires you to authenticate smtp through them.  In other words, say I have my own email:  jason@charlottezweb.com.  If I wanted to send/receive from that account and I was using Earthlink as my isp, I would have to configure Outlook to use earthlink's mailservers to kinda "proxy through" in order to connect to mine.  That used to be the case at least.  I believe I have to use smtp.earthlink.net and authenticate with earthlink login info and THEN have it connect to my mailserver and authenticate there.

I have a client that i simply can't get through the damn Earthlink portion of it.  I know his email is fine on my end b/c I can test it.

Anyone using a correct setup to do what I described?  I'll give you a choc chip cookie  :)

Hmm. Been Drinking but...

Cant think of any reason why they would force you to go through their pop3 to get you your pop3.

SMTP is different and if that is what you mean, then in the UK freeserve transparently direct all port 25 traffic through their own smtp server. To them this has the advantage of preventing people running their own SMTP server (probably forbidden in their AUP) and forcing them through their own smtp server, which is correctly configured and no chance of being an open relay.

I really cant see any reason for them to do something similar with port 110(pop3) traffic though.

If its an smtp problem though, click services manager in WHM, and theres an option to run an instance of exim on port 26, and you can get your client to set their email client to use port 26 for incoming mail. If it genuinly is a pop3 problem, I appologise for spouting rubbish.

charlottezweb:
It's a known issue with a lot of ISP's who purposely block port 25 to require you to use their smtp servers to filter mail.  (as best as I understand the problem).  And no, I don't believe Prodigy or Yahoo are on the list of ISP's who do this.

I don't really wanna mess with my server though because I know I've fixed this problem in the past with someone else on earthlink...I just don't know if something's changed since then.  I'll possibly pass along your advice Ben, b/c I think I read some other suggestions for something similar.

Ben_S:
Only thing I can think of is asking them to telnet to each server and seeing what they connect to.

Eg

telnet charlottezweb.com 25

and

telnet charlottezweb.com 110.

If they really are proxying pop3 traffic then that is madness, theres no logical reason to do so. Even AOL dont piss about with pop3.
