-------- Original Message -------- Subject: setting up mail and/or sendmail to use third party SMTP gateway. From: RThimble@xxxxxxxxxxxxxxxx To: fedora-list@xxxxxxxxxx Date: 02/06/2008 12:28 PM
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.
