Is there a way to set a bypass string or code? Some string of characters within subject or body that allows a message to bypass spam checks.

Why do you want to do that?

Why not whitelist the address if you want to avoid spam checks?

Or create a custom spamassassin rule to give your keywords a low spam score?

What problem are you really trying to solve?

I have an EFA server that serves multiple remote domains. Periodically i need to send out test emails, usually the telnet test to test mail flow on the various remote mail servers. Occasionally i will tweak postfix settings and its annoying to do tests and they get flagged for spam. I have been white listing my email, but my to's and from's can change depending on the task at hand. I just found it cumbersome to make a white list entry for these tests. I guess i was spoiled with the barracuda allowing this feature.

Im going to play with spamassasin keywords to see if that can accomplish my goal. Thank you for the TIP, i will post my findings in case anyone else might be interested in that.

Yes, then for that, the easiest solution is to create a custom spamassassin rule in your local spamassassin file.

You can add a magic word to your subject and give it a weight of -100 which will definitely pass the filter.

I’m not at a computer, so I can’t dig up one of my rules easily, but there are examples in the forums, or you can look at the existing rules under /var/lib/spamassassin/...

Let us know if you get it to work, or if you need help.

I got it working, exactly what i wanted. THANKS!

a few things:
1) the file i added the rule to: /etc/mail/spamassasin/local.cf
added at end of file:

body BYPASS_RULE /thestringforbypass/
score BYPASS_RULE -100
describe BYPASS_RULE Bypass Rule

2) the describe description does not seem to show up but the rule does work

3) I read somewhere else that im supposed to run sa-update and sa-compile to get the rule working, however i just restart mailscanner and the rule starts working.

when should sa-update and sa-compile be ran and why?

Thanks again!!

1/ correct place.

2/ to update the rule descriptions, go to "Tools and Links", and select "Update SpamAssassin Rule Descriptions" under the Tools section. You'll have to do this every time you add a new rule, or change a rule description.

3/ yeah, that's what I read, but I'm not sure what that is actually for. At a guess, I think it is for the rules in /var/lib/spamassassin/ You'll see two directories there, the source files and the "compiled" directly.

changes to local.cf seem to get picked up immediately.

when should sa-update and sa-compile be ran and why?

Normally this runs once a day: /etc/cron.daily/mailscanner (/usr/sbin/ms-cron DAILY -> ms-update-sa)

When you add or update rules, you can add them to the generated compiled rules which speeds up SpamAssassin https://spamassassin.apache.org/full/3. ... ompile.txt
