There are several parameters in dovecot.conf that can be adjusted to
prevent the problem that you're concerned about...
# Should each login be processed in it's own process (yes), or should
# login process be allowed to process multiple connections (no)? Yes
# secure, espcially with SSL/TLS enabled. No is faster since there's
# to create processes all the time.
login_process_per_connection = no
# Maximum number of login processes to create. The listening process
# usually stays at login_processes_count, but when multiple users
# in at the same time more extra processes are created. To prevent
# we check only once in a second if new processes should be created -
# of them are used at the time, we double their amount until the
limit set by
# this setting is reached.
login_max_processes_count = 128
