process repeats with the next recipient, except that sendmail changes from root to ben and
back again. If there is no C line preceding an R line, the previous C line??™s value is carried
down:
Cgeorge
RPF:/u/users/george/mail/archive
RPF:|/u/users/ben/bin/mailfilter ?†? controlling user is george
The form of the C line in the qf file is:
Cuser ?†? prior to V8
Cuser:eaddr ?†? V8.1 through V8.7.5
Cuser:uid:gid:eaddr ?†? V8.7.6 and later
The C must begin the line and be immediately followed by user, withno intervening space.
If no user follows the C, any prior controlling user is cleared and the identity that is used
reverts to that specified by the DefaultUser option (?§24.9.32 on page 1000). If present, the
user is the login name of the owner of the ~/.forward or :include: file that yielded the
address in the next following R or E line. If user is the name of a user who is unknown to
the system, prior to V8.7.6 and prior to V8.8 the effect was the same as though it were
missing. Beginning withV8.8 and V8.7.6, an unknown user causes the identity to become
that of the uid and gid. Beginning withV8 sendmail, an optional eaddr might be last. If
present, the eaddr gives the address to use for error messages.
