Hello Sorry, but I got lost in tunning (the server handles a lot of mail) or my brain isn't working properly anymore...
main.cf: virtual_transport = lmtp:inet:10.10.10.5:24 lmtp_destination_concurrency_limit = 20 lmtp_destination_recipient_limit = 1 #in dovecot in lmtp I have: process_min_avail = 20 I am trying to set the sender who sends mail to my server to be able to send only 100 recipients in one mail Is this a wrong setting: default_destination_recipient_limit = 100 default_destination_concurrency_limit = 100 others smtpd_client_connection_count_limit = 200 smtp_connection_reuse_time_limit=400s
