Sendmail problem

Jeg har et problem ved min mailserver.. Jeg bruger sendmail på redhat 8.0 - Når jeg sender mail fra min webmail fungerer det stort set til alle adresser, men når jeg sender fra outlook bliver den afvist. Jeg har sat fuld log på og her er resultatet når jeg prøve at sende en simpel mail fra outlook:
