I'm hoping that someone knows what I'm doing wrong.
night, yes I mean with webmail. I prefer not to use IMP, as I have used it before and has been nothing but problems for me. If I can set up Outlook Express I'll be much happier in my familiar surroundings...
This is the error I keep receiving:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'webmaster@domain.com'. Subject 'Re: Hey.', Account: 'webmail.domain.net', Server: 'webmail.domain.net', Protocol: SMTP, Server Response: '553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79
