I should add that all the mx names resolve with nslookup and a telnet mx4.hotmail 25 does work

The mx4 name changes, but the rejection is always the same. It would be nice to know what the unknown error is Does anyone have any idea what is causing the problems I am currently using OpenBSD 5.5 with sendmail (I know I should update it but I haven't got around to it yet)
