rate limit outgoing emails

TGM

Hello everyone,

does someone added an rate limit for the outgoing emails to grommunio? At this moment we are using policyd-rate-limit at our mail server. I did not checked if this is possible with grommunio too. But then I think the web app is out of focus for that, because it is only in the postfix sasl process?

Everything runs through the SMTPD (postfix) so it should also work for internal mails if thats what you are after.

EDIT: ahh now i get it, because the "sasl_username" is only used as it seems o_0.. ok.. and no way to change that?

maybe that? https://www.postfwd.org/

thats a interesting point and hint. I just saw in the policy documentation:

"limit_by_sender: Apply limits by sender addresses if sasl username is not found. The defaut is False."

Maybe this works. I will try out.

Okay, I solved this problem. 🙂 Here is what I did:

I installed policyd-rate-limit via pip3

zypper install python3-pip pip3 install policyd-rate-limit cp /usr/lib/python3.6/site-packages/policyd_rate_limit/policyd-rate-limit.yaml /etc/policyd-rate-limit.yaml

In the config file I set "limit_by_sasl" to False and "limit_by_sender" to True. Then I added in /etc/gromox.cfg outgoing_smtp_url=smtp://localhost

Now the emails which are sent via SASL and via Grommunio Web are seen and counted by policyd-rate-limit and I can configure limits regarding to the addresses or some defaults.

Best, Tobias
