I am setting up tmail as a delivery agent for sendmail. I would like to
have new mail delivered to a MIX inbox. I ran into a bit of a sang with
the set gid flag on the directory.

/u/us/fl/testub/INBOX by UID 11195
Mar 26 10:44:36 twooften tmail[11632]: delivery to /u/us/fl/testub/INBOX
unsafe: can't deliver to setgid file
Mar 26 10:44:36 twooften tmail[11632]: error in delivery
Mar 26 10:44:36 twooften sendmail[11631]: l2QGgSof011573: to=<[EMAIL
PROTECTED]>, ctladdr=<[EMAIL PROTECTED]> (0/0), delay=00:02:08,
xdelay=00:00:00, mailer=local, pri=210577, dsn=4.0.0, stat=Deferred: local
mailer (/usr/local/sbin/tmail) exited with EX_TEMPFAIL
The set gid flag is propagated from the parent directory when the INBOX
directory is created. The inbox create works, but the delivery fails in
the delivery_unsafe function. This quick hack on tmail.c seems to fix
it. Is this the best way to allow an INBOX directory to have the set
gid flag set?
