Default Using sendmail in a cron job

Greetings,

Since sendmail is running by default, I'd like to have the results of cron jobs emailed to my external email address rather than my username.

Is there any special tweaking (other than lots of coffee ) to allow this?

I've never dealt with sendmail before.

you'll need to edit /etc/aliases. Say you want to redirect all roots emails to .. here@there.com, you'd put the following in that file
Code:
root here@there.com
then run 'newaliases' to rebuild the aliases db

Thanks. Any way to add a subject line and make sure the log file, say, is in the body of the email rather than an attachment?

Default And now, domains...

Trying

Code:
mail -s "test" me@external-email.com
failed because my internal domain (on a LAN) was used as the identifying mail address, as machinename.LAN

I'm a bit confused by reading the man pages for hostname, setdomainname, myname, and so on, but I need to preserve DNS / DHCP for my machine, since behind a router.

Ah, networking...

I *think* this will solve it:

All you have to do is to edit as root the file /etc/hosts and include a fictitious FQDN for your machine. For example, the machine GX300 with IP number 192.168.0.7, could have as the fictitious FQDN GX300.test.net, and be entered in the HOSTS file as follows:

Code:
192.168.0.7   GX300  GX300.test.net
Then set the host file to query files before dns.
