Disable specific email from Rpamd checks

PavelK

Hi, I need help setting up mailcow. Because rspamd is significantly slowing down sending a large number of emails - specifically my newsletters, which are about 150,000 - I need to disable all checks in rspamd for a specific email address

I tried setting a complete bypass of all modules in:
/opt/mailcow-dockerized/data/conf/rspamd/local.d/settings.conf

sendmails_sender_bypass {
from = “sendmail@mydomain.com”;

apply {
symbols_enabled = []; # disable all filters
soft_reject = false;
reject = false;
greylist = false;
add_header = false;
subject = "";
priority = high; # Rspamd rule takes precedence
}
}

But no success. It doesn’t work..
Please, does anyone have a working solution?
Thank you

Mailcow is not suitable for mass sending. There are better solutions for this job (which can coexist next to mailcow):

Hi esackbauer, I also use another sophisticated software for creating newsletters, managing emails, campaigns, etc.
We use Mailcow as an SMTP server for sending, just like listmonk uses it. I’m solving a problem with the sending speed. RSPAMD checks every email sent and the sending time is about 30 hours. If I forcibly turn off checks in RSPAMD for the entire mailserver, I send 150,000 emails in 5 hours. That’s why I’m looking for a solution to turn off checks in RSPAMD only for a specific email. However, parameters such as DKIM, DMARC and SPF must remain ….
Thanks for any idea ….

I can only recommend to use a different host to send these mails. Your IP might get burned/flagged/blacklisted and regular mailcow users might be affected.
You could simply use one of the commercial mail relays like smtp2go or mailgun (as sender dependent transport in mailcow) which will better support you in sending mass mails.
Or run your own relay service as a small postfix container on a different IP adress/host.
