Everyone,
I have been getting bogged down and confused with the documentation on
setting up mail to send to a SMTP gateway. The problem is there is no
internal MX record(s) in DNS and we will not be adding any. I want to send
output to my corporate email account from our snort sensors when rules
are changed through oinkmaster. Any ideas on where I can start would be
useful.
Thank you
What I think you want to do is setup your local sendmail to usea a
"smart relay host" This can be accomplished two ways:
edit /etc/mail/sendmail/cf and look for:
# "Smart" relay host (may be null)
DS
and change it to
# "Smart" relay host (may be null)
DSmail.mydomain.com
then issue the command "service sendmail restart"
That is the easiest way. The "better" way is to edit the file:
/etc/mail/sendmail.mc and find:
dnl # be sent out through an external mail server:
dnl #
dnl define(`SMART_HOST', `smtp.your.provider')dnl
dnl #
and change it to:
define(`SMART_HOST', `mail.mydomain.com')dnl
Note the quotes are ` and '
Then issue the command "make restart"
You would, of course, change "mail.mydomain.com" to the name of your
local smtp server.
