Sendmail Relay

[Rodney Davis]

Hello all,

I am using a cobalt raq4 with redhat.  I have several virtual sites
running on my machine, each with their own email accounts.  Many of
these users want to use the smtp server to send mail but can't because
they use dynamic ips.  That means I can't set the relay domains in order
for them to use the server for sending mail and they get their email
returned with an unable to relay error message.  Can I put them into my
etc/mail/trusted-users file and have them be able to use the smtp server
or is there something else I can do?

Thanks
