Re: [courier-users] Strange sendmail problem

[Christophe G. <gre...@ze...>]

Well, I checked the log again, and I noticed what I think is the source of =
the problem :

5287  execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "testuser2"], ["S=
HELL=3D/bin/bash", "TERM=3Dxterm", "USER=3Dinfo", "MAIL=3D/var/mail/testuse=

sendmail should have uid 0, not the user one.
It checked for the Nth time,
=2Drwsr-xr-x  1 root daemon 26352 2005-11-15 10:52 /usr/sbin/sendmail

It HAS suid, and it's on the root partition (no nosuid flag).
I really don't understand why the suid bit on the exe don't work :(
