Hello,

has someone already tested the dovecot-proxy with more than 10 nodes? or someone knows anyway if is it officially supported up to a certain number?

There is no limit really. Proxies work standalone and are not linked together so you can have as many as you need. We have customers that have 20+ proxies running.
