You can set up the unix server by editing /etc/sendmail.cf (or similar) and finding the DS section. Un-comment the line to make it like the following:-
Code:
DSmyrelay.mycompany.com

This should be a mail router and should allow you to send stuff normally from any sendmail/mail/mailx command variation. You will also need to check that you can talk to the server on port 25 (smtp) Try the following:-
Code:
telnet myrelay.mycompany.com 25

You should get a connected message and wait on input. Typing quit should get you out. If you attempt pauses then times out after 30 seconds, there is a firewall blocking you or a routing problem. If it refuses you straight away, then it is not a mail relay.



I hope that this helps.

mconnect(1)							   User Commands						       mconnect(1)

NAME
mconnect - connect to SMTP mail server socket SYNOPSIS
mconnect [-p port] [-r] [hostname] DESCRIPTION
The mconnect utility opens a connection to the mail server on a given host, so that it can be tested independently of all other mail soft- ware. If no host is given, the connection is made to the local host. Servers expect to speak the Simple Mail Transfer Protocol (SMTP) on this connection. Exit by typing the quit command. Typing EOF sends an end of file to the server. An interrupt closes the connection immedi- ately and exits. OPTIONS
The following options are supported: -p port Specify the port number instead of the default SMTP port (number 25) as the next argument. -r "Raw" mode: disable the default line buffering and input handling. This produces an effect similar to telnet(1) to port number 25. OPERANDS
The following operand is supported: hostname The name of a given host. USAGE
The mconnect command is IPv6-enabled. See ip6(7P). FILES
