#
# Tightly configured MTAa require that a caller sends a real DNS
# domain name that corresponds the IP address in the HELO/EHLO
# handshake. This is used to verify the connection and prevent
# spammers from trying to hide their identity. If the DNS and IP don't
# match, the receiveing MTA may deny the connection.
#
# Here is a deny example of Net::SMTP with the default "localhost.localdomain"
#
# Net::SMTP=GLOB(0x267ec28)>>> EHLO localhost.localdomain
