Postfix options

Last week I got call from one of my colleagues complaining about the amount of spam she's receiving, so I installed SA and implemented some restricted options in postfix

smtpd_recipient_restrictions =

but later she called complaining that she cannot send emails using our SMTP server so for me it was what the hell is going one? later I found that Postfix is picky about the order of your options so if you do reject_non_fqdn_hostname before permitting sasl authenticated users, those authenticated will not be able to send emails.

and this was new to me.

Rules of war (in a nutshell) Since the beginning, humans have resorted to violence as a way to settle disagreements. Yet through the ages, people from around the world have tried to limit the brutality of war. It was this humanitarian spirit that led to the First Geneva Convention of 1864, and to the birth of modern International Humanitarian Law. Setting the basic limits on how wars can be fought, these universal laws of war protect those not fighting, as well as those no longer able to. To do this, a distinction must always be made between who or what may be attacked, and who or what must be spared and protected.
