An error occurred while sending mail. The mail server responded: 5.7.1 <marc.bunya@e-denen.net>... Command rejected. Please verify that your email address is correct in your account settings and try again. I have checked all the settings with my ISP. I even deleted the original account then added a fresh one with the settings as told to me by my ISP. No go. Security settings are Connection security: None and Authentication method: Encrypted password (this is what the ISP recommended) POP mail server. Port 110. Outgoing SMTP server Port 587 (again as per ISP instructions). MY ISP tech support has run out of ideas! Any suggestions? I can receive email on this account but cannot send.

re :Authentication method: Encrypted password (this is what the ISP recommended) Set to 'Normal Password'. Username is usually the full email address.

Thank you. Problem solved. The ISP fixed it on their side, so I don't know exactly what the problem was or how they solved it.
