I have used Greylisting before and I now it can be setup to automatically whitelist a sender if the sender passes the check, that is if the sender is frequent. Is this possible with ProxMox Mail Gateway? Maybe @tom ?
 
Yes, AFAIR there is a cache. Please note, a properly configured sender should never get greylisted.
 
Did I understood correct, that properly configured means, it has a valid SPF record and SPF check is activated? As mailservers may be properly configured also without having a SPF record and SPF check showed, that it run in trouble also at/with big companies, who seems to forget about their SPF records, because of not used such often in the internet.
