Could it be that some mailers (notably in the UK) strip the
"From " line, or don't add a "From " line?
And if so, could it be that they use some other method to authenticate the
mail, like:
From: Real Name <Authenticated_user_name>
instead of the usual:
From Authenticated_user_name Date
And what happens if sendmail receives a message without a "From " line.
Does it append one itself? What username and date does it use?
And if sendmail doesn't add any "From " line, what does /bin/mail
(the normal mail delivery program) do with it? Does it append the
"From " line? What username and date does it use?
Does it parse the <...>?
Inquiring minds want to know. Thanks.
