Hestia as only emails services

Hello, I would like to configure hestia to ONLY provide mail services (webmail, imap / pop3 / smtp, dkim, ssl). Do you have any particular recipe? I have tried to install nginx + exim + dovecot + mysql + proftpd + bind + spamassasin but when I want to use the webmail it gives me the following error:
“400 Bad Request Request Header Or Cookie Too Large”
I would not like to install apache if it is not necessary for the configuration I need.
PS: The nginx configuration also brings me problems, since it does not put the port in the domain configuration file and I have to add it by hand. This happens when I create them or when I activate the ssl.
Ubuntu 18.04 + hestia 1.0.6
Thanks

Can you share your installation string?

bash hst-install.sh -f -a no -v no -j yes -c no

Basicly -f should not be needed, can you please write out the commands? On mobile here.

The 400 (Bad Request) status code indicates that the server cannot or will not process the request because the received syntax is invalid, nonsensical, or exceeds some limitation on what the server is willing to process. It means that the request itself has somehow incorrect or corrupted and the server couldn’t understand it. The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method . Therefore, it prevents the website from being properly displayed. The main thing to understand is that the 400 Bad Request error is a client-side error.

The cause of 400 Bad Request error can be a wrongly written URL or a URL that contains unrecognizable characters. Another cause of the error might be an invalid or expired cookie. Also, if you try to upload a file that’s too large. If the server is programmed with a file size limit, then you might encounter a 400 error.
