iftocc(1)
NAME
iftocc - check for blind carbon copies
SYNOPSIS
iftocc [ okaddr ... ]
DESCRIPTION
iftocc reads a mail message from its standard input. It
exits 0 if $RECIPIENT is listed in a To or Cc field, 100
if not. Addresses are compared without regard to case.
If you list some okaddrs, iftocc will use them in place of
$RECIPIENT. It exits 100 if none of them are listed in To
or Cc.
- For example, with qmail 1.03 and above, you can put
- |bouncesaying 'I do not accept Bcc.' except iftocc
- into your .qmail file to reject blind carbon copies (including messages from mailing lists), or
|condredirect me-blind except iftocc- to forward all blind carbon copies to me-blind.
- WARNING: If you create a .qmail file to invoke iftocc,
make sure to add a line specifying delivery to your normal
mailbox.
