Panix Help System: Sending mail via Panix

Sending Mail via Panix

To prevent Panix's mail servers from being used by spammers, we have changed our SMTP (outgoing mail) servers to require authentication in most cases. This means that you need to log in to send mail, not just to receive it.

Do I need to use SMTP authentication?

You need to turn on authentication IF:

you're hooked up to a cable modem or a non-Panix DSL line, or
if you're on the Internet from a hotel, office, or public network (assuming the hotel or office isn't a Panix customer themselves), or
if you're dialing into Panix through most of our dialup lines.

In other words, you usually need SMTP authentication, nowadays. You don't need to use SMTP authentication if:

your office network is using a Panix corporate IP Internet connection (SDSL or T1), or
if you're using an ISDN line and terminal adapter to dial into Panix, or
if you are using the Panix Webmail interface to compose your messages.

How do I set up SMTP authentication in my mail program?

SMTP Auth is now available on all of our outgoing mailhosts. We've tested our implementation of SMTP-Auth with several programs, and it should work with almost everything out there. We know for a fact that it works with the following:

Outlook Express for Windows (5.0 to 6.0 inclusive)
Outlook Express for Mac (5.02)
Apple OS X Mail v1.2.3 (v551)
Netscape 4.75 and up (Windows and Mac)
Pine 4.40 (UNIX)
MS Outlook 2000 and 2002 (Windows)
Entourage 10.0 (Mac OS X 10.1)
Mozilla 0.95 (UNIX, cleartext, no SSL capability) and 1.x (Win/Mac/UNIX, SSL support added)
Eudora 5.1 and up (cleartext at least)

We know that it doesn't work with the following:

MS Outlook 97
MS Outlook 98 (claims to have support, but it doesn't seem to work)
Eudora 5.0 and below
Netscape versions below 4.75

If your mail program isn't on the lists, give it a try and let us know! Send a summary to staff@panix.com and we'll add it to the appropriate list.

Sure, but how do I set it up?

Oh, right. Our SMTP-Auth Setup page gives click-by-click instructions for most popular email programs.

If your program isn't listed on that page, here's the Panix-specific info you'll need:

Set your outgoing mail server to:
mail.panix.com
If your email address ends in "@panix.com", just use your email address as the username. (Your Panix login by itself will also work.)
If your email address ends in "@access.net", you need to enter your full email address including the "@access.net" part.
If you use cmail1.panix.com for your incoming mail, you need to enter your full email address as the username. If your mailbox has more than 1 address associated with it, call us for assistance.
Use your regular Panix password as the password.
Some providers block port 25 on other systems. If you can't use port 25, try port 2525 or port 587 instead.
If you are using secure SMTP (that is, SSL-wrapped SMTP) you should use port 465, unless you're using Eudora, in which case you should use port 4650..
