Good day Tom...

You sir just solved the issue - DoFakedUseLocalDomain was selected - the hotmail test worked this time....

youre welcome ;-)

When the test comes from hotmail - it says it is spoofed... when I reply to it - it sends it to a default address - not back to hotmail... I can not send anything to the outside world - only locally - and everything says it is spoofed - which is what I am guessing is why I can not email out....

disable smtp vrfy is not selected in eims
