FWIW, in both Postfix and Exim, it's a one line config change to do individual deliveries. qmail has always only done individual deliveries. If you want to do VERP, Postfix and qmail have options to do the bounce address munging in the MTA, so your mailing list sends one message with many recipients but when it goes out on the wire it's expanded to individual copies with unique bounce addresses. I continue to believe that whatever problem was solved by multiple recipients went away decades ago. These days mail is a tiny fraction of net usage. R's, John PS: if someone is going to say what about super long delay paths like to the moon, you shouldn't be using SMTP on them at all. Try something like batched compressed uucp. _______________________________________________ Ietf-dkim mailing list -- ietf-dkim@ietf.org To unsubscribe send an email to ietf-dkim-le...@ietf.org
