Port 25 is available but no 220 promt is coming. So I assume not enough smtp or amavis deamons on port 10024 10025 are available.Postfix logs that fact.

anvil_status_update_time = 600s anvil_rate_time_unit = 60s smtpd_client_connection_rate_limit = 50 smtpd_client_connection_count_limit = 10 smtpd_client_message_rate_limit = 50 smtpd_client_recipient_rate_limit = 10 smtpd_client_event_limit_exceptions = $mynetworks, "IP of my mailfirewall" default_process_limit = 500wenn ich also 20 smtps konfiguriere und im log dann "max connection rate 18/60s" lese, dann scheint es mir naheliegend, dass das 20er limit in Summe überschritten wird. d.h. wenn ich mit "-o smtp_client_connection_count_limit=10" das limit auf 10 setze und mehr als 20smtp konfiguriere, dann erhöhe ich die Wahrscheinlichkeit, dass für nutzmails mehr Ressourcen verbleiben. Und mit smtpd_client_event_limit_exceptions = $mynetworks, "IP of my mailfirewall" kann ich davon ausnahmen machen?
Nope. 18/60s heißt 18 Verbindungen in 60 Sekunden und bezieht sich auf rate limits. Der Wert unter "max connection count" ist der gesuchte, der geht allerdings wohl nicht über 4.
Wie bereits vorher erklärt läßt sich das Problem (alle Verbindungen belegt + Before-Queue-Filter) nicht so einfach lösen.
