550 5.7.1 Access not allowed Cannot send email on windows server
Posted by PremiumReseller.com on 02 April 2008 04:25 PM

You send email but receive error message 550 5.7.1 Access not allowed

There are 2 possible reasons:

1. Merak Mail Server block access by a black list filter (the sender ip address in spamhaus.org spam blacklist) or

2. Access is rejected if originator's domain is local and authorized option is not turned on.

Local users have to authorize themselves in order to send email.

You need to configure "My outgoing server requires authentication" and provide login details in email client software.
