mailfromd should also be able to do this. Going to apply this soon myself

Hello,

I am trying to come up with a way to have individual quotas per user for the submission service. Similar to what I could achieve with Postfix and policyd.

More specifically, the quota I am most interested in, is limiting the number of messages a single account can send within a given timeframe. Ideally, I'd also like to limit the number of total recipients within a given timeframe, to mitigate the loophole of adding multiple recipients to a single message.

Example: account Y is allowed to send 500 messages per 60 minutes, with a maximum of 2000 recipients overall.

What would be the best path to take?

Thanks!

Gerry If postfix is handling your submission service you can have a look at postfwd

https://www.postfwd.org/

I use it to limit sending of emails, recipients, etc, etc

I am using Postfix as the relay host behind dovecot-submissiond. Unfortunately, unless I'm missing something, submissiond does not seem to be able to add the SASL username to the message headers, so I don't have a good way to distinguish sending users on the relay server.

Cheers,

I don't use dovecot-submissiond

I use standard postfix submission and postfix recognizes the dovecot SASL username

Perhaps this helps?
