Question Cloudflare SSL for Webmail - too many redirects

[mathi_reg]

Hey guys,

my goal: I want my webmail.mydomain.com to be secured. mydomain.com is the Plesk Management Domain where I manage my subscriptions and other domains.
First: www.mydomain.com is secured with SSL and works fine. I'm running cloudflare as a DNS manager to point to the IP.

My Cloudflare SSL/TLS Setting is set to "Flexible" at the moment.



Again: my plesk admin on mydomain.com is working fine with SSL.

These are my settings on mydomain.com inside of Plesk. I'm not sure why webmail doesn't work.
FYI: If I remove the webmail record from Cloudflare or uncheck the "Proxied" it does fix the "ERR_TOO_MANY_REDIRECTS" but the SSL is not active.



Any ideas here? Thank you in advance,
Matt

btw. setting the Cloudflare Setting to "Full (strict)" as pointed out here is also not the solution: A website hosted in Plesk fails to load when Cloudflare is used: ERR_TOO_MANY_REDIRECTS
