It checks that there + are no blind (bcc) recipients in the message. Every envelope recipient + must appear either in a To: header line or in a Cc: header line for this + condition to be true. Local parts are checked case-sensitively; domains + are checked case-insensitively. If Resent-To: or Resent-Cc: header lines + exist, they are also checked. This condition can be used only in a DATA + or non-SMTP ACL. + + There are, of course, many legitimate messages that make use of blind + (bcc) recipients. This check should not be used on its own for blocking + messages. + +PH/10 There is a new ACL control called "suppress_local_fixups". This applies + to locally submitted (non TCP/IP) messages, and is the complement of + "control = submission". It disables the fixups that are normally applied + to locally-submitted messages. Specifically: + + (a) Any Sender: header line is left alone (in this respect, it's a + dynamic version of local_sender_retain). + + (b) No Message-ID:, From:, or Date: headers are added. + + (c) There is no check that From: corresponds to the actual sender. + + This feature may be useful when a remotely-originated message is + accepted, passed to some scanning program, and then re-submitted for + delivery. It means that all four possibilities can now be specified: + + (1) Locally submitted, fixups applies: the default. + (2) Locally submitted, no fixups applied: use control = + suppress_local_fixups. + (3) Remotely submitted, no fixups applied: the default. + (4) Remotely submitted, fixups applied: use control = submission. + Exim version 4.52 -----------------
