Fix a Mail.app incompatibility with Exchange 2000 Apps
Jaguar's mail application has a problem communicating with Exchange 2000 when sending mail. I received the error 5.5.4 Invalid Address when sending any mail message. This is the result of Exchange being too picky about the format of the EHLO message used by Mail. A workaround is documented on Microsoft's Support website.

The workaround involves using the MetaEdit program to change a setting in the Exchange server to permit periods or spaces at the end of the EHLO command. Note that you need to reboot the Exchange 2000 box after applying the fix, a step that is not documented in Microsoft's tech note. Taking these steps fixed the problem.
