Have a look at http://spf.pobox.com/wizard.html?mydomain= , there's an SPF wizard with lots of explanations, and this wizard is very similar to the SPF form in ISPConfig.

This has really helped. Now just to be on the safe side, all I need to do is set the SPF record for the hoster's site (eg. www.mylastname.dom) and just add hosted sites to the MX parameter?
Or should I also set up the SPF record for all the sites that I host?
Their is a company who filters all mail to remove spam (has the 1st MX record), and then forwards it to the ISPConfig server for our customer.
Is it possible to setup ISPConfig (SPF record) so that it can only receive mail
from this external company? It only has to be done for that customer only.
For all the other customers we rely on spamassasin
