question about default postfix config

[tobiasp]

Hi,

I saw that efa setup sets

Code: Select all

postconf -e "default_destination_recipient_limit = 1"

.
what is the reasoning behind this?

cheers,
Tobias

Off the top of my head it is to prevent excessive throttling/defers from remote SMTP relays. I'll have to look back to see exactly what prompted this limit.

thanks for your reply. the reason why I ask is that this setting has more implication than I first thought. I was in the process of setting up a "destination_rate_delay" and wondering why it was not working, but having an destination_recipient_limit of 1 means some settings are per recipient and not per domain... (see http://www.postfix.org/postconf.5.html# ... ient_limit) so essentially a rate_delay would be mostly useless in throttling emails. maybe setting destination_concurrency_limit would be more suited?

You can go ahead and raise this limit if you like. I'll study this and see about using the other setting instead as a future default.
