Sendmail Switch (Sendmail 8.11.x) from sendmail requires
that /etc/mail, /var/spool/mail, and /var/spool/mqeue be owned by smadmin,
and in group smadmin, and sets these directories up accordingly.
Linuxconf 'Check some file permissions' says
The state of the system is not in sync with the current/updated
configuration. You are allowed to make it current, or continue with the
current configuration. You can alsolook at the things that will have to be
done to make the system current.
Looking at things to be done says:
Changing owner of file /var/spool/mqueue to root.mail
Changing permissions of file /var/spool/mqueue from 40715 to 40755
Changing owner of file /var/spool/mail to root.mail
Changing permissions of file /var/spool/mail from 40735 to 40775
Changing owner of file /etc/mail to root.root
Changing permissions of file /etc/mail from 40715 to 40755
This causes sendmail to stop sending mail:
Aug 3 10:02:13 services sendmail: e73E2DH01721: SYSERR(smadmin):
Can't create transcript file ./xfe73E2DH01721: Permission denied
Aug 3 10:02:16 services sendmail: e73E1Ds01709: SYSERR(smadmin):
Can't create transcript file ./xfe73E1Ds01709: Permission denied
Directory permissions have been fixed so that linuxconf and a
correctly-configured system are now in agreement.
