HELP!! Newbie going nutts due to email issues!!

[za-zi.com]

Hi There,

I just bought a .com.... za-zi.com and have just recently loaded the website....

I am using the web based plesk.

Up until a few days ago my mail was working fine. I could send and recieve my mail with out any issues.

The last few days however, i am unable to receive mail. I can send from all my @za-zi.com mail addresses but i can not receive.

when i send a mail to my za-zi.com email I get the following error message:
PERM_FAILURE: SMTP Error (state 9): 503 This mail server requires authentication. Please check your mail client settings.


What is going on?????
Does anyone have a solution to my problems??????
Please do let me know if you do.
I really really really need to get these emails working again.

Enable smtp authentication in your mail client, you can use your pop3/imap login and password to authenticate yourself to the smtp server.

but maybe your ISP disabled the mail relay on this server, so I advice you to contact them also.

and now....
my website won't even load!!
all the files are there on the server but the site won't load

this is so frustrating
and my "tickets" NEVER get answered

I see your website is running, but something is missing in your frames.

I'm sure your ISP can solve your mail issue, so try to contact them a little harder, if they keeps ignoring your tickets go find another webhoster.

but why don't you use the smtp server of access provider?
