Current versions of sendmail use 2 separate configs (sendmail.cf &
submit.cf) to get round the old problem of the sendmail binary being
installed setuid root. Basically this means when you send mail,
sendmail is invoked with the submit.cf which connects (normally) to the
sendmail daemon (using sendmail.cf) running on the same box. The daemon
process then either does local delivery or sends on to the next hop.
Take a look at /etc/mail/README - first section. This means either you
need either a sendmail daemon running, or to change the submit.cf to
send somewhere other than your local box (ie your isp).
For first option, set sendmail_enable to NO in rc.conf. The provided
sendmail.cf will attempt to deliver directly to other sites. If you
want to go via your ISP, edit your sendmail.mc file. Copy freebsd.mc to
your_hostname.mc & edit the line:
dnl define(`SMART_HOST', `your.isp.mail.server')
change your.isp.mail.server appropriately and remove the leading 'dnl'
(dnl introduces a comment in m4. "delete to new line"). Then run make.
See the comments in /etc/mail/Makefile
For the second option, copy & edit submit.mc and change
FEATURE(`msp')dnl
to
FEATURE(`msp', `your.isp.mail.server')dnl
The first option delivers local mail locally & sends off non-local mail.
The second sends off all mail. Depends what you want.
Sendmail will complain if it can't determine its hostname fully qualified.
One last thing - sendmail isn't really intended for
"echo howdy | sendmail anotheruser "
though that usually works. Let 'mailx' do the work of prettying it up
for you. eg
"echo howdy | mailx anotheruser "
