Hi, i use smtp_tls_security_level = encrypt - if remote site have mx like
mx 10 mail1 without tls mx 100 mail2 fake-mx with no open port postfix detects lack of tls on mx10goes to mx100 and waits maximal_queue_lifetime. i don't like fake mx as they create a long delay. i could reduce queue lifetime but in general thats bad for real systems with temp issues. how do you handle this? Stefan
