Re: smtp;550 Denied by policy
if what you said are right then how can more than 200 users send new e-mail out said the company.. the problem only related to one or two user.
Today I made a test:
1- I let the user login to ” OWA – Outlook Web Access”
2- send e-mails from his contact list
what I notices that he can send e-mails without having the “SMTP” message. However, when he try to send from MS outlook he got the “SMTP” message..
it is really strange..
I was thinking that may be Groupshield has to do something in blocking but when the user can send from his OWA then their is no problem in the groupshield.
Also, I try to access the dnsreport.com and I got this message
