smtp security
Per the Cox email I changed the POP3 setting to 995 for all my @cox.net addresses. Can I change SMTP to some other number than 25 to enhance security on emails sent?
I changed my SMTP settings per the email to 465 w/ SSL and now I get the following Error message
25 still works fine sending, but not 465
The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'b****2@cox.net'.
Subject 'Test'
Server Error: 550
Server Response: 550 5.1.0 Authentication required.
Server: 'smtp.cox.net'
Windows Live Mail Error ID: 0x800CCC78
Protocol: SMTP
Port: 465
Secure(SSL): Yes
