Thanks for all the replies.
Please keep in mind that i am currently at home trying to solve the problem and my ISP is AOl.
I shall say as far as i have got using different scenarios.
Using smtp.orangehome.co.uk and firstname.lastname@example.org
as the log in with port 25 i cannot connect at all.
Using the above settings with port 587 I get the password box pop up so i enter email@example.com
as the user name and i enter my password which works fine on sites like mail2web. The box just keeps popping back up as if i am entering the details wrong. I have also tried *****.fsworld.co.uk and *****.fsworld.co.uk@fs as the user names.
If i try to use my ISP SMPT server smtp.uk.aol.com with port 25 and ****@aol.com with my aol password as my outgoing mail server details i get this error message.
The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider.
The rejected e-mail address was 'firstname.lastname@example.org'. Subject 'asdasd', Account: 'pop.orangehome.co.uk', Server: 'smtp.uk.aol.com', Protocol: SMTP, Server Response: '553 5.7.1 <email@example.com>: Sender address rejected: not owned by user *****@aol.com
', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC78
If i try the same details as above with port 587 the result is the same. Checking "this server requires a secure connection (SSL)" makes no difference.
thanks again for spending your time on this.
