I have recently had to restore my laptop and since then cannot send emails through WL Mail.  I am currently getting the following error message:

The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Live Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '*** Email address is removed for privacy ***'.

Subject 'test....'
Server Error: 554
Server Response: 554 <cpc11-enfi15-2-0-cust194.hari.cable.virginm.net[94.175.122.195]>: Client host rejected: Access denied
Server: 'smtp.enfieldscouts.org'
Windows Live Mail Error ID: 0x800CCC79
Protocol: SMTP
Port: 25
Secure(SSL): No

I have tried changing the port to SSP but that doesn't work (it says account does not support it), I have read through a few others that seem to have had the same issue but have still not got it working.

Please help as it's urgent I can fully access this account.

Many thanks
