SYMPTOMS
The Microsoft Mail Gateway to SMTP displays this warning:
CAUSE
The name provided in the "mail from" received by the sending host is incomplete or contains a null value:
[rx] mail from:<>
RESOLUTION
None necessary: this message is informational only and requires no action by the Mail Administrator. The Gateway continues to process mail.
MORE INFORMATION
The example below shows an address without a beginning "<" and an ending ">". This log file was created using the undocumented -CD option which tells the Gateway to display debug information.
