Please allow me to ask for clarifications:

local <ip>         -->  Local Dovecot Server IP address
local_name <name>  -->  Connecting client username
remote <ip>        -->  Connecting client ip address

Please correct accordingly, if necessary. Thanks!

I just found in Dovecot logs:

dovecot: master: Warning: service(imap-login): process_limit (100) 
reached, client connections are being dropped

This must be it!  So, I guess I could add to my config, for example:

    service imap-login {
        service_count = 1
        vsz_limit = 64 M
    +   process_limit = 500
    +   process_min_avail = 2
    }

Sounds right? (Ref.: http://wiki.dovecot.org/LoginProcess)

By the way is there a way to show/monitor (e.g. using doveadm) the 
current number of login processes used?

Thanks for everything!
