comment Attribute caching of dovecot maildir boxes over NFS
@Andrea I have no experience with mail+nfs, but in general, with acxxx you steer how quick changes on the server should be visible on client. This is in case, if changes from one client should be visible on an other client. If mail server is the only client which does the updates and should see them, then it should be safe to have some caching there.

why you turned off all kind of attribute caching (acregmin=0,acregmax=0,acdirmin=0,acdirmax=0) ? You simply enforce NFS client to attack server with getattr requests.

Then it's probably NFSv4.1. Check response to CREATE_SESSION->csr_fore_chan_attrs->max resp size

comment I'm unable to symlink a directory into /var/www/html
check that your /home/myuser/myrepo/webfiles can be accessed by apache/httpd user. Usually, /home/myuser directory has a permission 700.

comment what will be the primary IP address of my system if i have two NIC can i change it?
there is no primary interface. There is one bound to your host name and the one which has default route. It may be the same interface. So the question from @alxgomz is absolutely valid: define primary IP.
