I thought I had learned how to send a message to a distribution list without the whole list showing up on everybody's copy, using a construct like: To: abritrary-listname: listname; or To: arbitary-listname: , , ...;. The recipients will not see the text between the colon and the semi-colon. All they'll see is: To: arbitary-listname: ; So I sent a message addressed as follows: To: mailusers:big-list; Where big-list is in my aliasfile. The mailer returned the following error message: Subject: Returned mail: Host unknown ----- Transcript of session follows ----- 550 ... Host unknown My aliasfile didn't get expanded. I have no idea where @mailusers came from. So, I repeat my original problem. Using MH, how can I send a message to a large list of addressees without everyone seeing that same large list?
