Sending Email from Outlook Express - Error

[Anika]

When I try sending emails from Outlook Express I'm getting this error
"An unknown error has occurred. Subject 'Email Problems - Aplus - Update', Account: 'admin - Aplus', Server: 'pro47.abac.com', Protocol: SMTP, Server Response: '554 5.7.1 Forbidden for policy reasons', Port: 465, Secure(SSL): Yes, Server Error: 554, Error Number: 0x800CCC6F"

Please tell me what i can do to solve it. I was recently using Godaddy Server to send and receive emails but have switched to Aplus and it was after the change we started having this problem.

Outgoing SMTP Port number is 465 (SSL Ticked) and my Incoming Port  number is 110

FYI
OS: Windows XP SP2
Anti Virus - Trend Micro SMB

I think you need to contact the mail provider for the correct settings for outlook express.  I do see its a secure server and that may be the problem, but i'm guessing.

I agree with lostcoast.  Where did you get port 465?  Are you sure that's right?

please check your incoming & outgoing port address 

old mail id settings

POP3:25
smtp:110

new mail id setting

POP3 :465
SMTP :995
