Hi

In the configuration readme it says to do:

m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf

but (unless I'm being stupid) it seems to have been deemed too obvious to
say where to put the resulting file.

sendmail(8) says that -C specifies to use an alternate file, but doesn't
say which file or files are used otherwise.

In a fresh install of OpenBSD 4.3 I have

/etc/mail/localhost.cf
/etc/mail/sendmail.cf
/etc/mail/submit.cf

which seem to have been generated from

openbsd-localhost.mc
openbsd-proto.mc
submit.mc (?)

Is only sendmail.cf used (and the others are examples)? or are the others
used at different times (eg local invocation of sendmail vs. SMTP mail).
Which other files might be read (other than ones that are referenced by
these, obviously).

More generally, where can I find good sendmail documentation? I have
found through google http://www.sendmail.org/m4/readme.html , which is a
reformation of the configuration readme into html, but isn't linked to
from the front page of sendmail.org. I have also found the Linux Network
Administrators Guide ( http://tldp.org/LDP/nag2/x-087-2-sendmail.html )
very useful, but wonder what else might be out there that you might
recommend.

Many thanks,
viza

same place as where the config.mc is.

If you intend to use the resulting config.cf as sendmail's configuration
then it goes where sendmail expects to find its configuration file and
with the correct name.

Because you can use *any* file located anywhere in the filesystems.

Did you read /etc/rc.conf?

Haha, you are as cryptic as the documentation!

Well, as long as it is on a filesystem that is mounted when sendmail
starts.

What I would like to know is where is the normal place to put it?

Perhaps this is an OpenBSD policy specific question, or perhaps the
sendmail developers have some preference or suggestion. I guess that
this would be a compile time constant.

Yes I did. It said:

# For normal use: "-L sm-mta -bd -q30m", and note there is a cron job
sendmail_flags="-L sm-mta -C/etc/mail/localhost.cf -bd -q30m"

But it didn't expand upon what "normal use" meant, and where the
configuration would be read from in the absence of -C.

Since the above starts both a queue runner and an SMTP listener, I guess
that this governs both of these situations, but what if, for example
/usr/sbin/sendmail or /usr/libexec/sendmail/sendmail is invoked? Must
all invocations of sendmail (eg: by php) check have the -C flag? I would
hope that writing to the standard input of a sendmail process would
function the same as writing to port 25 on the loopback interface, but
might this not be the case if my listener is invoked with -C ?

Thanks in advance to anyone who can help explain this.

Try:
sendmail -d0.10 -bv root
