For some reason I can receive emails but when I try to send and email I get the following error.
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[email protected]'. Subject 'Re: Instant Messaging', Account: 'mail.thumb.net', Server: 'mail.thumb.net', Protocol: SMTP, Server Response: '550 relay not permitted', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
Now I use this email address at home and at work. When I use it at work it is fine and I can send out fine but when I try and send an email it just sits in the Outbox.
I have contacted my ISP and he can not figure out why it will send out at work and not at home.
I have had my computer checked for Malware (through this website) and it is all clear now but I still have this one problem.
So any help would be appreciated.
Thanks so much,
