Could any one explain to me if there is a way to restrict open relay and still allow POP3 users to access their email on Ex 5.5 SP4? I have gone to the Routing restrictions tab and check the " Host and Clients with these IP addresses" but as soon as I did this my Phone started going nuts with calls from a few POP3 users that I have. Please help this is quite urgent! Thanks a lot in advance Juan Ibarra Windows Systems Administrator Phone: (650) 930-5474 Fax: (650) 930-5606 jibarra@xxxxxxxxxxx www.marimba.com <<...OLE_Obj...>> The Software Change-Management Company ------------------------------------------------------ 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 ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: smcleod@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
