We currently operate our e-mail by using Netscape's E-Mail Servse which resides "behind" an SGi Gauntlet V.3.2.
The problem that we have is the following:
A user with the following email client configuration:
USER ID <userid>@<subdomain>.<domain>.com
sends an email to any user on the Internet.
i.e From: <userid>@<subdomain>.<domain>.com
The gauntlet firewall accepts the mail and forwards it into the
The trusted email server opens an SMTP connection with the firewall and
the firewall opens an SMTP connection with the destination host...................... that is where the striping of the subdomain occurs.
That is at the recipient's side the "from" field shows:
<userid>@<domain>.com (the subdomain is lost)
