[IMail Forum] SMTP32.EXE Boom!

[Mike Goetz]

This is a strange problem.  We have about 200 users on our corporate mail server, which is running a Windows NT 4.0 Server machine with IMail 6.06.  We have created group aliases and have office users in their own respective groups, but we also have an ALL_USERS alias that sends to everyone that has an e-mail address on the server.  Sending to the smaller branch office lists, no problem.  Sending to All_Users?  The mail from the client end just shows the mail went out.  But if you happen to be next to the IMail server when you send to All_Users you’d see a Dr. Watson application error box pop up that says “SMTP.EXE has failed” etc.  It seems to be related to a large number of users in a group alias.   Has this happened to anyone before?  Anyone know what it could be?  Should I investigate doing a list instead?   Also, on a related question, is there a way to secure these aliases so that only certain people can send to these addresses?  What I‘ve had our managers do is just type the alias addresses in the BCC field to hide where it’s going but that secret won’t last.    Thanks!
