Symantec Mail Gateway Blocking Incoming SMTP with 554 5.7.1
Got a Printer situated on a remote office wich can authenticate with user name a password, also a billing server wich can also authenticate with user name and password, before the addition of the Symantec Mail Gateway Appliance the authentication happened at the TMG layer, right now i have to place a publish rule on the TMG to force all SMTP on port 25 to the mail gateway in order for all my mail to be filtered. This is working great for users and ipad and iphones and every other device.
I am having issues with a Printer and a VoIP Billing solution wich needs to be able to send email for reporting reasons and the Printer is a MFP so it used to scan docs and send them via email.
The accounts are all authotized to send i can confirm by loggin in to the Outlook Web Portal and sending a fewa emails.
If i remove the Mail gateway and put the authorization back on the TMG all works again.
Printers comes from a PUBLIC IP, so does the VoIP Billing device, i can clearly see the connection been rejected at the anti Spam top rejected reports.
On the printer i have no errors but on the VoIP solution a i can a distinct error 554 5.7.1.
