Hi again,
Further to my earlier emails re: problems with dtmail and
sgid not seeming to work on 2.2-RELEASE (but working on
2.2-ALPHA).
I have just browsed through the CVS archive and found the
following:
In src/sys/kern/kern_exec.c
>1.47.2.2 Wed Feb 19 3:53:35 1997 by davidg
>CVS Tags: RELENG_2_2_0_RELEASE; Branch: RELENG_2_2
>Diffs to 1.47.2.1 ; Diffs to 1.51

>Brought in change from rev 1.51: preserve P_SUGID if {u,g}gid != r{u,g}id
>Note that this doesn't actually fix any known security holes, it just

Could this be causing my dtmail problem? I will patch my kernel
sources when I get home tonight and try it. Will send a follow-up
report.
Regards/Mark
