I'm trying to limit the number of users that have email access using their GW account.
I tried setting the "Default Class of Service" on the GWIA object to prevent SMTP Inbound and created a new Class of Service where I allowed a distribution list with every user that has access to email. This results on every connection to port 25 of GWIA to be closed with this message:
"554 IP connection rejected"

And this on the (verbose) logs:
14:57:24 656 DMN: MSG 444 IP connection refused: [::ffff:x.x.x.x] ()
14:57:24 656 DMN: MSG 444 SMTP session ended: [::ffff:x.x.x.x] ()
14:57:24 656 DMN: MSG 445 IP connection refused: [::ffff:x.x.x.x] ()
14:57:24 656 DMN: MSG 445 SMTP session ended: [::ffff:x.x.x.x] ()
14:58:25 656 DMN: MSG 446 IP connection refused: [::1] ()
14:58:25 656 DMN: MSG 446 SMTP session ended: [::1] ()

x.x.x.x = our inbound mail filtering box


Anyone had this problem?
