Hello,
Not quite sure I understand.. when a new account is created, the email that is sent should include a reset passwd link.
What sort of account did you create?
Also, if you run:
# mail -s Test you@you.com < /etc/issue
are you getting it? just want to make sure emails are in fact sent in general. If you are not getting it, you should look at /var/log/maillog to understand why. This is of course after making sure an MTA is actually listening on port 25.
Don't know if you chose to use Postfix, Sendmail, Exim or something else but they should all work fine.
When doing:
# netstat -plnt |grep 25
You should see something like:
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 2190/master
tcp6 0 0 :::25 :::* LISTEN 2190/master
in my case, postfix is used so the process is called master.
