OK, did all that. I renamed and deleted badmail. Used the DOS command and got rid of 63000+ files in 5 minutes. Now I tested sending to frank@xxxxxxxxxxx (does not exist) and with the NDRs disabled as previously mentioned the message did not go into the badmail directory. On the other hand it generated a warning in the Appl Event Log as follows: Event Type: Warning Event Source: MSExchangeTransport Event Category: Connection Manager Event ID: 756 Date: 1/28/2004 Time: 11:12:16 PM User: N/A Computer: XXXXXX Description: A non-delivery report with a status code of 5.1.1 was generated for recipient rfc822;frank@xxxxxxxxxxx (Message-ID <000001c3e61e$14123210$6545a8c0@GORAN>). Data: 0000: 46 05 04 80 F..? Oh it is so wonderful when you go and look it up http://support.microsoft.com/default.aspx?scid=kb;en-us;308323 I had my diagnostic logging on. Duh. So now no badmail files and no events clogging up my application log. Wonderful just what I want.

First stop SMTP service, then rename badmail folder into badmail1, and create the new folder and name it badmail (you don't have to rename it but it could help). It will prevent system from freezing. Then delete all badmail files through explorer (may take hours!, so plan it carefully), and then delete badmail1. These files are messages that never found recipients, so they will keep coming. You should check the folder periodicaly or make a script to empty it on regular basis (some messages could be real ones-sender misspelled the recipient address). Read MS KB 315631-it's nice thing. These files can give you a lot of info about what's going on with your messaging system. Regarding warning message send me the full message with its source. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------
