Outlook 2007 XP sending problems

[morphy]

This is the message I get when I try to send an email with Outlook using
Windows Live Mail-
An unknown error has occurred. Account: 'pop3.live.com', Server:
'smtp.live.com', Protocol: SMTP, Server Response: '500 Unsupported command.',
Port: 25, Secure(SSL): Yes, Server Error: 500, Error Number: 0x800CCC62
- does ANYone know what the heck this means???
Im pretty sure it has something to do with my smtp port settings which I
assumed were set by default???? Can someone help me with this??

Some ISPs are blocking outbound e-mail traffic (i.e., SMTP traffic across
their domain that does not go to their own mail servers) that uses port 25.
This is not only to comply with RFC 2476 ratified over 11 years ago but it
coincidentally (for awhile) was a deterrent to infected hosts running mailer
trojans to spew spam. Instead try port 587 for SMTP (outbound).

Unfortunately the vast majority of e-mail clients still default to port 25
for SMTP; however, RFC 2476 was ratified back in December 1998 which said
that port 25 was for use only by MTAs (mail transfer agents; i.e., mail
servers) and was not intended for use by MUAs (mail user agents; i.e.,
e-mail clients). The RFC recommends port 587 for MUAs. ISPs have been slow
to adopt the RFC. E-mail clients have been even slower.

Also make sure the account you defined in Outlook authenticates to the SMTP
mail host.
