Mail Server Stops Working When Switching To Cloudflare DNS
Upon switching over to Cloudflare, the mail server that I have set up with PostFix and Dovecot stops working. By “stops working”, I mean that I am no longer able to send or receive mail from my Thunderbird client. As soon as I switch back to Digital Ocean’s nameservers, I am able to receive the mails that had queued up while on Cloudflare’s NS.
So the mailserver doesn’t stop working entirely, however when I try to authenticate/login to my mail account through Thunderbird, to send/receive, the connection just times out/server doesn’t respond.
My mailserver has DKIM and SPF records in use.
Any help would be much appreciated!
