Vista - Yet Another Can't Send Email Question

Hate to Ask But i cant seem to find anything:

I have Checked the Email / Virus Protections - They are Not Interfearing
User Name / Password is All correct.
Checked to see if the SMTP Required a Secure connection Etc. All is fine.

But this is the Error i get when it trys to Send Email.

The rejected e-mail address was 'slambert 18@cogeco.ca'. Subject 'TEST',
Account: 'pop.cogeco.ca', Server: 'smtp.cogeco.ca', Protocol: SMTP, Server
Response: '501 Bad address syntax', Port: 25, Secure(SSL): No, Server Error:
501, Error Number: 0x800CCC78

I can Recieve Just fine. Any help would be Appreciated

Thanks in Advance!

Well, the error message is rather self-explanatory:
the email address "'slambert 18@cogeco.ca'" has improper
syntax since it has a space after 'lambert'. Spaces are not
allowed in email addresses.
