    One of my users wants to be able to send out a newsletter every month to about 1200 recipients (and yes, it's double opt-in, no spam, easily unsubscribable). This turned me to custom config postfix using
    smtp_destination_concurrency_limit = 2
    smtp_destination_rate_delay = 1s
    smtp_extra_recipient_limit = 10
    I then wanted to use a transport mapping as described here,
    transport_maps = hash:/etc/postfix/transport
    but I see ISPConfig already uses virtual transport_maps in

    Is there an easy way to implement options like these below (in ispconfig)?
    polite unix - - n - - smtp
    turtle unix - - n - - smtp
    and a /etc/postfix/transport file with
    Code: polite: polite: turtle: turtle: turtle: turtle: turtle: polite:
    and then in add
    polite_destination_concurrency_limit = 2
    polite_destination_rate_delay = 0
    polite_destination_recipient_limit = 5
    turtle_destination_concurrency_limit = 1
    turtle_destination_rate_delay = 3s
    turtle_destination_recipient_limit = 2
