[rt-users] $RT::MailCommmand = smtp

[Steve Poirier]

Ok i understand what you're talking about:

220 max.inet-interactif.com ESMTP Sendmail 8.9.3/8.9.3; Wed, 8 Aug 2001
12:29:16 -0400
helo steve
250 max.inet-interactif.com Hello root at ns2.inet-interactif.com
[216.218.2.249], pleased to meet you
mail from: nobody at jfdkjfkdjf.bog
501 nobody at jfdkjfkdjf.bog... Sender domain must exist
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And your prob is:

There is no way you can make the host to be resolved?? I don;t really
understand what you mean about your host is on the company network..) do you
have control of DNS records for this domain?
