How to create an email address on a linux box?

Hello folks,

How could I create an email account on linux box (sendmail)?

Imagine I have a project management application which process email
message and add them as a bug to the project.

I want to create an email address per project, when the user create a
new project.

May you please give me a clue how to do this?

Thanks in advance,

You might want to try postfix instead, it may be easier. You will have
to read the postfix manuals and how toos though. There are rails
samples that make use of postfix.
