I'm using Zimbra as Relay to Exchange in the same network.
My sent e-mails are going with this header:
Received: from mx.facilitynet.com.br (webmail.facilitynet.com.br [184.108.40.206])
These hostname differences can identify my server as spammer ?
Guys, i'm worried!
Thanks in advance,
mx.facilitynet.com.br is the hostname of relay
webmail.facilitynet.com.br is the reverse of 220.127.116.11.
