Hi,
It's written in the doc that "smtpd_client_connection_count_limit" is
about the number of simultaneous connections from a client, but it's
also written that "It must not be used to regulate legitimate mail
traffic."
If this is not the way, then how can one regulate the simultaneous
connections from one client?
Is there a theoretical maximum?
Setting it to 0 means unlimited? ("To disable this feature, specify a
limit of 0.")
What side effects can be expected?
Unfortunately the service (which is made of 4 servers) is behind a
firewall which hides the real client IPs so these 4 servers see only 1
client (the firewall) and the expected mail count is 4+ million per
day.
Thank you!
