Sorry, my mistake.
I meant mod_proxy.

Open the domain details and add the following under "additional Apache directives".

Code: Select all

SSLProxyEngine On
ProxyPass /.well-known/ !
ProxyPass / https://server.tld/webmail/
ProxyPassReverse / https://server.tld/webmail/

RequestHeader unset Accept-Encoding
RequestHeader unset Origin
RequestHeader set Referer https://server.tld/webmail/
Just change "https://server.tld/webmail/" with your webmail URL.

Hello,
Thanks for your reply.
The default webail is https://domain.tld/webmail. I want use https://webmail.domain.tld
I know can use Configuration --> Webmail --> Keep domain name this function.
But I use https://webmail.domain.tld it's will secure warning.Because letsencrypt only for https://domain.tld.
Could I use https://webmail.domain.tld?
