Hello ISPConfig Family, If someone install latest version of ispconfig with all instructions, and all the mails go to Spam Category for gmail and outlook, what should he do ? I have seen before someone talk about PTR Record. Hope to find someone explain what should to do.
Look at the header of the mail and see why it is classified as spam. Search for DKIM, SPF, PTR and deploy these. Use these websites to configure your domain and mailserver: https://www.mail-tester.com/ https://mecsa.jrc.ec.europa.eu/ https://ssl-tools.net/mailservers https://hardenize.com
