i'm executing (with popen) /usr/bin/mail from cgi program (written in C).
cgi's are started with suexec. when mail is started it ends with that:


Oct 10 08:32:19 serwer sendmail[6570]: g9A6WJh06570: SYSERR(admin):
collect: Cannot write ./dfg9A6WJh06570 (bfcommit, uid=50107): Permission

executing same command from same user by hand works fine.
/var/log/httpd/suexec shows:

[2002-10-10 08:26:59]: info: (target/actual) uid: (admin/admin) gid:
(users/users) cmd: cgimail.cgi

so looks it works right.


any ideas?


sendmail has root suid in /usr/libexec/sendmail but looks like it doesn't
work that case. is it possible?
