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
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.
