you can put this in /etc/spamassassin/local.cf

header   MESSAGEID_LOCAL  Message-Id =~ /\.local>$/
score    MESSAGEID_LOCAL  1
describe MESSAGEID_LOCAL  Message-Id contains ".local" TLD

and reload whatever you plug into your MTA.

It works. I already got a mail by ...vn.local

The base SA ruleset is optimized to detect spam with a score of 5.0. If you raise that score, you will allow more spam to come through. If you lower that score, you will see more legitimate messages blocked as spam. Make sure you know what you are doing before you change this score.

I would score your MESSAGEID_LOCAL rule closer to 3 or 4 at the most. This way, it still makes a big contribution to the score, but messages will not be blocked based on it unless there are other spam signs. The best idea with new rules is to add them with a low score at first and keep an eye on them for at least a couple of days to make sure that they are performing as expected before raising the score.

Remember that Amavis has its own settings for required_score and message markup. Any of those settings in the SA config files will be ignored.
