I have my normail mail server on one box and i have installed xeams on a brand new centos server.
for now i have two mx records. one for the email server and one for xeams. This is a production env and can not afford to loose any emails.
I have the xeams installed as a firewall and the diags work fine. But when i try to send an email via the xeams server, they get rejected " ERROR: RCPT not accepted from server" (using https://www.wormly.com/test_smtp_server - great tool BTW)
They only way i can get it to work is to set the SMTP relaying to "OPEN relay" in the xeams "SMTP Server Configuration". Is this what i am supposed to do? I think that is bad, but not sure what else to do , to get it working?
