depends on the usecase / workload having dovecot as proxy for other imap-backends and 1 process per connection will heavily raise up process-count and memory-overhead while memory may be needed for the imap-backend (like dbmail) and datanases process_limit = 15 client_limit = 300 this way you can have 4500 proxy-connections and use most time not more than 4-5 processes
