Where does Outlook get "From" information?

[Tony R.]

Strange question but I'm getting a email from a client and whenever I reply
back to him I get a undeliverable message back. When I look at the "From" in
Outlook the email says:

From: Jane E Doe ([email protected])

and thats who it replies back to but when I look at his signature on the
bottom of the email he has it listed as "(e-mail address removed)" which would make
more sense, and when I use that email it works just fine. So my question is
where is Outlook pulling the "From" information is that my contacts, his
contacts, when he setup his email, or where does it get it? I'm trying to
figure out how it could be wrong there and where to fix it.

Thanks
Tony

If a Reply-To header is included, replies will default to that e-mail
address. If the Reply-To header is missing, the From header is used. So
look in the headers to see if there is a Reply-To header. If there is,
perhaps the sender specified the wrong e-mail address to put in that header.
Tell the sender to not bother using the Reply-To header if it is given the
same value as the From header. There is no point in having a Reply-To
header unless it has a different value than the From header.

Signatures are just some text within the body of the e-mail. Nothing in the
body of an e-mail is used to address replies to that e-mail. Just the
headers are used to identify the sender who then becomes the recipient in a
reply.
