Hello,
Encountered an odd error I was hoping can receive help
on...
Using Outlook on Exchange Server. User receives an email -
can open it and view message body however the TO, CC and
SUBJECT header white box fields are blank. Has anyone
seen this before?
Thanks,
Andrew.
You don't mention if this behavior is present in all received e-mails or
only in one particular e-mail.
If you read RFC 2822, "Internet Message Format", you'll see the To, Cc,
Bcc, and Subject headers are all optional. They may appear 0 or 1
times. They are in the *data* that the sender composes and sent in the
DATA command to the SMTP server (RFC 2821, "SMTP"). So the sender can
specify anything they want to put into these headers. They don't even
have to be inserted in the data. They don't even have to contain valid
syntax for an e-mail address; e.g., they could simply be used to spew
more spam text. These headers are not used to deliver the e-mail. The
RCPT TO command(s) issued by the e-mail client to the SMTP server are
used to to specify the recipient.
Presumably SMTP was involved somewhere since I doubt this behavior (by
the sender) would be possible if the sender was using the same
organization's Exchange server as the recipient. You don't mention if
the message came from within your Exchange organization or from outside.
