Hi, folks.

This morning, sendmail (8.14.2-1.1 running on CentOS 4.6) barfed.
When i tried to start the server, it threw the following error:

451 4.0.0 /etc/mail/sendmail.cf: line 91: fileclass: cannot open '/etc/
mail/local-host-names': World writable directory

I also got a similar error regarding /etc/mail/trusted-users in
submit.cf.

Having to get this server up and running quickly, I googled for a
possible solution. One post suggested replacing line Fw/etc/mail/
local-host-names with line Fw-o /etc/mail/local-host-names in
sendmail.cf, and Ft/etc/mail/trusted-users
with line Ft-o /etc/mail/trusted-users in submit.cf. I made those
changes and ... all was good!

My questions are: 1) what might have happened to cause this, where
other sendmail instances set up similarly on other boxes have no
problem?, and; 2) can there be any ill affects from making these
changes?

Many thanks.

The first thing I did was to check the perms of /etc/mail, and indeed
they were 0755. All of the files in that directory were also correct.

As I said above, the tweaks I made, based on another post, did work.
But, I'd still like to know why the problem occurred, and if there are
any issues associated with the tweaks.
Why would these be questions for CentOS? It's sendmail that's
complaining. Any help/insights would be much appreciated.

The message should be read as:
I can open the file but I *refuse* to open the file with too broad write
permissions in one of parent directories.

Use the command below to trace cause of problems in submit.cf
[ it is most likely the same as in sendmail.cf ]:
/usr/sbin/sendmail -Ac -d44.4 -bv root

# ls -ld / /etc /etc/mail

I beleive you have to check every component of the path when you get
such an error.

OK, point well taken. I just thought somebody on this list might have
encountered the same issue.
