have a look at the description of the 'dns' option.
It has to do with controlling to whom the mail is addressed too.
The aka option enlarges the list of properly formed addresses by,
in your case, allowing mail to e.g. firstname.lastname@example.org. Without it
such mail would be dropped, only mail to email@example.com or
to firstname.lastname@example.org would get delivered. (well I think to have
read that mail to e.g. dirk@your-local-host-names get delivered
anyhow, not sure though)
