Can you please explain the two options a bit more?
For the first,
seehttps://www.postfix.org/postconf.5.html#default_destination_rate_delay
but this is not recommended, since it applies to all transports, even
ones you probably don't want to rate limit.
For the second, it is unlikely you or anyone else should be changing the
default. The suggestion is most likely the result of a misunderstanding.
Is default_extra_recipient_limit not limiting the number of recipients in a
given message ?
No. And, what did you have in mind anyway?
- Limiting the recipient count of incoming SMTP message envelopes?
- Limiting the recipient count of outbound SMTP deliveries
(splitting the envelope for larger messages by doing multiple
deliveries each with at most that many recipients)?
My concern is a customers trying to send email to 100s of recipients and
getting blocked for bulk mailing so
- Limiting the recipient count of outbound SMTP deliveries
