I'm not saying that Blat don't work.   I'm just saying I get the error message.  I'll ask the email admin to look into relaying from the inside.  Thanks for cluing me in on the meaning of the error msg. Don - the code you were gracious enough to send me.  I tried it, and it creates a tmp file in c:\inetpub\mailroot\pickup\temp, but I don't receive it via email.  Is there something else I need to do to have it emailed to me? And, on the telnet, I think I need to add a CR\LF at the end of the commands.  It works as long as I can hit the <Enter Key> at the end of each command.  But in the batch file I need to emulate hitting that <Enter Key>. Thanks
