Question Connection to Mailserver doesnt work

[depesch]

Server operating system version

Debian 11.7

Plesk version and microupdate number

18.0.53

Hi,

Yesterday I switched the name servers of my domain dennispeterschneider.de from Hetzner DNS to Cloudflare. My Plesk instance/my host is "plesk.dps-infra.de" and is not managed by Cloudflare but at netcup.de. Since i switched to cloudflare for dennispeterschneider.de, a connection in Outlook or Apple Mail to my mail server no longer works. E-mail retrieval via webmail works. Unfortunately, I cannot find the error and assume that I have set everything correctly. Can anyone give me a tip?

Hi @depesch, thank you for posting. These may help:

Resolved - Cloudflare, DNS and Mail

I own domain.de and it's hosted on my Plesk server xxxx.startoserver.de rDNS used to be xxxx.startoserver.de and my hostname in Plesk was also xxxx.startoserver.de. In cloudflare I had the following records: A domain.de --> IP (proxied) A mail.domain.de --> IP (DNS only) MX --> mail.domain.de...

Did you enable CloudFlare proxy for your domain dennispeterschneider.de?
