Blocking mails from domains that are less than 30 days old

General Discussion
1

Is there any way using wither postfix or preferably spamassassain to block emails from domains that are less than 30 days old?

Add weight to these Spamassassin rules

FROM_FMBLA_NEWDOM14 - From domain was registered in last 7-14 days
FROM_FMBLA_NEWDOM28 - From domain was registered in last 14-28 days
FROM_FMBLA_NEWDOM - From domain was registered in last 7 days

i am not sure these rule are valid any more.

This rule relies on a DNS-based lookup service: fresh.fmb.la.

The last time the rule triggered on my system was 6/15/25

maybe my pfsense is blocking it :slight_smile:

Unfortunately this relies on a list rather than getting the information from a DNS request which I am not sure is possible even.

How does it work when you are setting up a new domain for a client?

currently there is no restrictions. If I use spamassassain I can use a points score for new domains on incoming emails.
