Regular Pleskian
Introduced the new option “Fix incorrectly set sender for outgoing mail” that significantly reduces the likelihood of outgoing emails landing in spam (if DKIM and SPF are also enabled and properly set up). If the option is enabled, Plesk fixes incorrect sender headers and the envelope-sender address for outgoing mail.
Could someone please tell me what problem this fixes, exactly?
I don't want to enable something that will attempt to fix something that isn't broken on my server unless I know it will only help and not hurt my setup.
How can I tell if this is a problem I have?
