I am running Exchange 5.5 SP4 on a W2K server SP1. Since installing SP4, it appears (could be coincidence)that I now regularly get notification of Outbound Mail Failures. The message states that the mail could not be sent because the 'host is unknown'. I am assuming that if I had any problems with DNS then no mail would get delivered. The Internet connection is working perfectly. Any help would be really appreciated
Thanks Phil Steele _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
