Yes, that's the only solution, I think.... -----Original Message----- From: Orr, Dale [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 07, 2002 8:00 PM To: Exchange Discussions Subject: RE: securing smtp
Human engineering problem. Disable/uninstall Outlook Express if you can't get the horsepower to forbid users to use it. -----Original Message----- From: Tom Meunier [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 07, 2002 9:52 AM To: Exchange Discussions Subject: RE: securing smtp Oh. Well, that's an RFC question. You're asking for how to let everybody in the universe EXCEPT your own people send inbound mail? That's just kinda weird. No way to stop it; they're just telnetting into your port25 like everyone else in the world. Unless you know what IP address they're hitting you from, and refuse those. -----Original Message----- From: Irfan Malik [mailto:[EMAIL PROTECTED]] Posted At: Thursday, March 07, 2002 7:16 AM Posted To: MSExchange Mailing List Conversation: securing smtp Subject: RE: securing smtp Thanks Tom, We are using e2k sp2 and w2k sp2. As well there is correction in my statement. "Some of my users using Outlook Express. I want users not to send mail outside or within LAN without authentication. I have controlled this for mails going to other domains but users still can send mails without authentication within LAN using Outlook Express. How can I secure that, any suggestion is request."

I would have gotten more specific, if you had said what version of Exchange you were using. That's important info. But "look it up in the FAQ" will get you there. In 5.5 it's in the properties of the IMC, to require auth. In 2000 it's in the properties of the SMTP Virtual Server or connector, whichever applies in your case. -----Original Message----- From: Irfan Malik [mailto:[EMAIL PROTECTED]] Posted At: Thursday, March 07, 2002 2:52 AM Posted To: MSExchange Mailing List Conversation: securing smtp Subject: securing smtp Dear all, Some of my users using Outlook Express.
