RE: SMTP Question
That's what I told them to do. Just trying to be supportive and hopefully right at the same time. I know they don't totally believe me, but they're going to try it anyway. The head Unix guy is looking for a SendMail 'how to do it' book right now. I have other applications that relay through the IMC. Of course they are all using a @crowley.com in the From address.

RE: SMTP Question
Hi Jim, The Unix box in question is configured in the IMC to relay. I have other applications that relay fine with @crowley.com in the From address. The Unix folks are going to configure their mail to use a @crowley.com address. Hopefully they can figure out how to do it. Thanks!
