After hours now of searching and searching, ive ran out of ideas. Im new to servers (sorry!) and im renting a VPS from GoDaddy for the next 3mos to get my feet wet. Had a 47% off coupon code, so i figured, GREAT time to try my hand at it.

That being said, WHM VPS Optimized v3, ive created a "master" reseller account, so as to install WHMCS and my site and all. Ive also setup a few email addresses through port 2083, in cPanel. I can send emails fine from Horde and the others, I can also send AND receive emails if i send from mydomain to mydomain - but external emails hotmail.com to mydomain.com get returned to sender with a smtp 550 error, Address Rejected.

Ive tried turning off SpamAssasin, and every other filter (all which are back at default), ive ran intodns.com's tools and mxtool box and all and i cant really get an idea of why this is happening, when i setup everything, i didnt do anything other than the defaults.

I also ran Mail Statistics inside WHM, and in Mail Rejection Reasons, it lists

Code:
Rejected MAIL: Access denied - Invalid HELO name (See RFC2821 4.1.1.1
Rejected RCPT: Please turn on SMTP Authentication in your mail client
Rejected RCPT: Please turn on SMTP Authentication in your mail client. mail3.gwcteam.com (gwcteam.com)
Rejected RCPT: Sender verify failed
Please...my fingers are killing me, ive searching everywhere.

*wanted to note this -- in the second rejection, it listed another domain i own in () that I USED to use for this VPS...could the DNS at that other domain pointing to this servers ip screw up the mail? im at a loss.. thanks in advance everyone.

Email - Can send mail out, but cannot receive mail

Hi everyone, after much exhaustion, im looking for some guidance. I have a VPS through GoDaddy (reseller hosting), created a main reseller account for myself in WHM and lastly setup three email boxes in cPanel.

Problem - I can send email out to say [email protected] and its received. However i cannot receive mail on my VPS hosted domain [email protected] I CAN send and receive mail from [email protected] to [email protected] on my VPS...so its just receiving mail from external sources. I sent a test one out from my gmail and it instantly gets rejected with a smtp;#550 error, Address Rejected.

Ive looked everywhere i could on the net and tried some things, but no success. I feel like its some small tweak that im missing, but im just stumped. Can anyone point me to how i can view a log for this, or steps to take to fix it?

Ive ran intodns.com and mxtoolbox and it looked ok?

Hello,

You're not being clear enough. If you are unable to send, are you meaning that you are unable to use Thunderbird / Outlook / Mac Mail (i.e. a remote email client) to relay your mail through the server? If that's what your'e saying, then:

1. What is the error that your Thunderbird / Outlook / Mac Mail (or whatever email client you use) returns back to you when you attempt to send mail to an external address?

2. Did you enable SMTP Authentication in your email client? You need to enable SMTP Authentication (in Microsoft Products it's called "My Server Requires Authentication" and is found in the Outgoing Server tab / More Settings.

you need to make sure that SMTP Authentication is enabled and that it is SMTP Authenticating with a valid email address / password of an account that exists on your server.

Yes. You should go to the DNS settings in WHM and set them to "Remote" for that domain or domains.

You should also check the DNS settings at the domain registrar end and check if the MX records are pointing to your "new" server correctly.
