TwitterThe online greylisting support page: https://support.plesk.com/hc/en-us/articles/213394809-How-to-configure-Greylisting# mentions the option -whitelist and uses it in a bit ambiguous way, so that one could be led to believe, that it is used to whitelist an email server. However this should be done with -domains-whitelist. Could you please clarify this in the documentation?
Also please mention somewhere that the domains are matched against the clients HELO hostname and not against its DNS name (which imho would make a lot more sense, since DNS cannot be forget by dynamic IPs, whereas the HELO can be trivially).
