Need help with Mail

[Robert Terry]

Anyone out there can help me? I'm having strange problem with this mail
problem. It's a problem ever since last Febuary, and I took over the this
machine just last month and am determined to get this fixed. It's not the
problem sending or receiving the mail messages...it's the problem reading 
the mail messages on MWMS machine. Whenever typing the command, 'mail',
to read mail messages and the error message said,  

	"mwms% mail: mailfile does not begin with a 'From' line"

Below is a sample taken from MWMS and MOS machines.

Unfortunately, I know little how to configure the sendmail configure file.
I would really appreciated showing me how to get this fixed.

Here's the legend on MWMS:

AST Premium 486/25 running on Interactive OS 2.0.2.
Don't know the sendmail's version.

Either reply here or email directly to my dependable mail station:

	email: terry at tcville.hac.com

				Really appreciated,
