chmod

Instead of doing this, you could just chmod g-w /, /etc, /etc/mail. The only problem is that apple seems to reset the permissions on / at every update. Still, as I understand it, it's better to change the directories to group non-writable than it is to add in the DontBlameSendmail stuff.

chmod (aka fix sendmail permission permanently)
Authored by: bluehz on Apr 22, '02 03:32:35PM

I was having lots of problems with the permissions on / being reset on a regular basis and I belive I finally discovered and fixed the culprit. Seems the cron daily task has a line in it that resets the permissions each time back to non-group writable.

I fixed it by opening /private/etc/daily and modifying the line that reads:

touch "${i}" && chmod 600 "${i}"

changed it to:

touch "${i}" && chmod 640 "${i}"

and I have not had any problems since.

Also - you don't necessarily have to "activate" sendmail to get it to work on an "as needed" basis - you just have to fix the permissions as above. A good example if this is the fact that I do not keep sendmail process running all the time - yet the crontab status reports are mailed out as needed by calling sendmail - so it is activated on an "as needed" basis and then retired again.

If you want to delve into the mail server realm I would recommend Postfix and Qpopper instead - supposedly much more secure.

chmod

Another idea is to modify /System/Library/StartupItems/Sendmail/Sendmail and add the following lines:

chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue

Now the permissions get right every time sendmail starts up (actually, put it before the command that starts up sendmail).
