Good thing I was playing with sendmail all this morning... =3Dop
Coincidentially, I was looking for exactly that functionality. The option
that sounds like what you're looking for is NoRecipientAction
("O NoRecipientAction=3D<value>" in the sendmail.cf file).
It seems that if a mail client sends sendmail an e-mail
without a To: field, you have three options (really four, but you shouldn't
really consider the fourth option -- it's deprecated):
- "None" (passes the message accross unmodified
-- breaks the protocol, yet it seems to be the default
behaviour on RedHat 6.2 systems. Dunno about later versions)
- "Add-To" (add a To: header with any recipients it can find in the
mail -- can expose Bcc: recipients)
- "Add-To-Undisclosed" (adds the header "To: undisclosed-recipients:=
;")
- "Add-Apparently-To" (deprecated -- only for back-compatibility)
=20
Which you use is dependant on what purpose you're using the mailer for, and
how private you wish the Bcc: headers to be. Personally, I use the "Add-To"
value.
OTOH, there is a header that lists the mail path and who the mail was
originally for -- it's called the "Recieved:" header, but I'm not sure if
that'd be reliable across MTAs.
