Thanks, I have been looking at those adjustments. My concern, is
that if Dovecot uses a process per imap or pop connection, 2048 is
not nearly enough for any significant email system.
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
one
# login process be allowed to process multiple connections (no)? Yes
is more
# secure, espcially with SSL/TLS enabled. No is faster since there's
no need
# to create processes all the time.
login_process_per_connection = no
# Maximum number of login processes to create. The listening process
count
# usually stays at login_processes_count, but when multiple users
start logging
# in at the same time more extra processes are created. To prevent
fork-bombing
# we check only once in a second if new processes should be created -
if all
# 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
