HI Tom;
These guys are correct, your mail server is not exchanging any
authentication but expecting it.
WHM and Cpanel use different mail tools depending in what exactly is
available and embraced/installed by your hoster.
http://www.cpanel.net/products/cpanelwhm/features.html
If you have it, use the WHM mail troubleshooter:
http://www.webhostingresourcekit.com/flash/whm/whm10_x_mail.html
Most web hosters use the WHM mail tool because of the many issues with
insecure mail scripts cgi hacked. This simply means that your server is
sending mail FROM ITSELF (not necessarily for/to the domain) using WHM.
1) MX for your domain (so that your new server will be used for MAIL XFER
[if you are already using another mail service and have a 0 or 1 priority MX
record, just add a second MX for your offsite mailer IP machinename (which
MUST match the reverse in-addr-arpa IP address and name the server presents
itself as PER the RFC)]
http://www.gregrobert.com/mxsetup.php
2) Mailer to allow specific IP addresses to access and relay without
authentication.
If you find you are not using WHM, but have another mail server, it's going
to be configurable within Cpanel or WHM also.
This is generally in /etc/mail or /etc/postfix and is usually called *relay*
something. But refer to specific documentation for your mail transport
tool.
I.E. google "How do I configure relay hosts in postfix" for instance.
GoDaddy does have ssh or ftp. You can change configuration files with ftp,
where you generally would be vim editing the file and restarting the mail
daemon. Generally CPanel and WHM have tools to manage everything available
on the server.
I am familiar with setting up Cpanel and WHM on servers as well as working
within them for various shops through the years. If you have questions you
can email or call me off list.
So much of the specifics of your hoster are guessed by us, wouldn't this
question best be crafted and packaged for their support email or process?
