I am trying to migrate my domains from cpanel and i did some testing to mail deliverability. Most times when i sent to microsoft (outlook hotmail) or gmail mail went to spam. (my droplet is new and not blacklisted)
i have set up reverse dns properly and also i added a dmarc record as following:
Webmin -> Servers -> Bind DNS Server -> Choose domain -> Choose type DMARC and finally i created the record adding 100 to percentage of messages to apply policy
After i did the following
Virtualmin -> Email Settings -> DomainKeys Identified mail and save.
My first question is if this is a proper way to create a DMARC and DKIM record. Should i do it manually for every virtual server? Second question is what else i can do in order to improve mail deliverability?
Thank you in advance
