Thanks.

I work at a web host, we tell people to change to 587 in cases where their ISP blocks port 25 connections attempting to leave their network, i.e. they are trying to stop spammers. -- John ___________________________________________________________________ John Murtari Software Workshop Inc. jmurtari(a)following domain 315.635-1968(x-211) "TheBook.Com" (TM) http://thebook.com/
