DKIM signs your outgoing emails with the use of an encrypted key which is used during verification by MTAs. It is the best method of protecting your emails from hackers and abuse. For Plesk to begin signing your emails each time you send a mail, you need to enable DKIM. Refer below-mentioned steps for How to generate DKIM record for my domain in Plesk server?
