I have several servers running applications on debian. Each has the packages it requires for the application, and no more.
Currently, none have mail sending capability. However, I would like the output of tools like cron to be mailed to me.
The servers are hosted at an ISP site that provides a 'smart relay' server I should use for all outbound mail.
How should I configure my debian servers:
- To permit local tools like cron to send mail, as something like email@example.com (I specifically do not want 'root@machinename')
- Not provide any inbound mail services
- Use the ISP's provided 'smart relay' for outbound mail
What package is good for such a 'minimal' mail service?
