annoying sendmail problem

    Lately a FreeBSD box we run in college has refused to allow any users but root to send email; here's the log messages it's been throwing out:
    Apr 5 12:34:59 netsoc sendmail[57241]: g35BYxWx057241: SYSERR(cluster): collect: Cannot write ./dfg35BYxWx057241 (bfcommit, uid=1003,
    +gid=25): Permission denied

    I've checked the permissions and ownerships on /var/spool/mqueue, /var/spool/clientmqueue and /var/mail and they all seem to be set correctly. The only thing I can think of is that this has happend since I cvsup'ed all the sources on the box, but I fail to see how that could effect this.

    Anybody else running 4.5-STABLE having these problems ?

    i also had that problem.

    the fix i found was that somehow, the "s" bit was removed from several system files that need to be suid for say email to work.

    so just set sendmails suid bit on and there are a few others that are needed too. i cant remember off hand. did you also notice you cant su to root? same thing chmod +s /bin/su or where ever it is.

    Regards,

    Paul

    ah grand that worked fine, /usr/sbin/mailwrapper was causing the problem.

    Didn't notice any problems with su though.

    very odd, I just upgraded and the same problem cropped up again :/

    I'm surprised there isn't more information about this since it's such a major problem.

    upgraded in what way? like cvsUP? or just a re-install/upgrade from the cd? the prob arises when it backs up your bin dir and then just copies the files back to bin i think at some later stage. it doesnt replace the suid bit on the proper files.

    i had probs using passwd aswell as su and mail till i checked all the correct files.

    it is truly odd. maybe one of us should contact them about it? :)

    u wanna do it or shall i?

    Regards,

    Paul
