Hi All,

I have a question about running a mail server on Linux. I use a Dynamic DNS service and I am trying to send and receive email to my Redhat box. I have questions about security.


Do the email accounts need to have user accounts on the box? Sounds like a dumb question.
I never ran email other than local accounts.

If I want to use my own domain what do I need to consider?



Sorry for such general questions. I really appreciate any help.


Thanks,

Luck
