[Exim] error -19: Remote host mc7.law5.hotmail.com [64.4.42.…

Hi All!

Since 2001-01-19 I can't send emails to any hotmail-Account.

The log say:
2001-01-24 15:30:07 14LRs7-0001zh-00 ** xyz@??? R=lookuphost
T=remote_smtp: retry time not reached for any host after a long

In this for all MX-Servers of hotmail.com

How can I cange the hostname of the HELO command?

Many thanks in advance
