How to don't spam-check for email recipient in amavis

Post by siuntung »

Hi Administrator Zimbra,

One of our users wants every email from the sender to be able to go into her inbox, without going through a spam check.
I don't know how to make it like that.
Please help me from Zimbra experts on this forum

Thank You

Regards,
Untung

Hi JDunphy,

Thanks for your reply, I have already execute like below

zmprov ma user@example.com amavisBypassSpamChecks TRUE amavisSpamLover TRUE

So how can I know whether the command was successful or not?

Can you try below commands after setting the value?

Code: Select all

zmprov ga <email-address> | grep amavisBypassSpamChecks
zmprov ga <email-address> | grep amavisSpamLover

sure like below:

zimbra@test:~/conf$ zmprov ga blabla.lay@blabla.com | grep amavisBypassSpamChecks
amavisBypassSpamChecks: TRUE
zimbra@test:~/conf$ zmprov ga blabla.lay@blabla.com | grep amavisSpamLover

Returning value as TRUE means those attributes are obeying in the system. Please post if you face any issue or if more config needed for the respective query.

Hi Untung,

You are welcome.

BTW, It's possible to look in /var/log/zimbra.log and see the SA headers so you know score and what rules fired.

I wrote something to parse this years ago that might help in the future.

Ref: https://raw.githubusercontent.com/JimDu ... ed_spam.pl

Usage is this (run from any user that has read permission of /var/log/zimbra.log):

Code: Select all

% check_rejected_spam.pl 
user is @ rules[0] ham[0] spam[0] discard[0]
usage: % check_spam.pl 
      [--user=<username>]
      [--ham|h ]
      [--spam|s ]
      [--discard|d ]
      [--rules|r ]
      [--option|o ]
    requires one of
       --ham | --spam | --discard
    where
       --ham will display only ham
       --spam will display only spam
       --discard will display not delivered email due to scoring
       --rules DO NOT display SA rules that fired
       --user will display only email destined for that user
 
Example of output looking for spam classified only without listing the individual rules that SA fires on

Code: Select all

% check_spam.pl --spam --rules
...
...
Score [14.206] To: b.lastname@example.com From: cloudmail@servermail.com
Score [ 6.204] To: j@example.com From: bouncebacks@ceotoday-magazine.com
Score [ 5.356] To: d.lastname@example.com From: grayrentaldisplays92@gmail.com
or discard would be

Code: Select all

% check_spam.pl --discard --rules
...
...
Score [38.188] To: j@example.com From: D2Wdv35nwY0cChwXgD@boiling.catenaliggette.xyz
Score [34.186] To: b.lastname@example.com From: 2zDDGyCSJ4riGneFHx@jump.catenaliggette.xyz
Score [34.186] To: b.lastname@example.com From: 4ySyUjJX1CSA2o2IJu@jump.catenaliggette.xyz
Score [47.419] To: b.lastname@example.com From: 25645-446682-200990-7089-b=example.com@mail.flexapain.world
Where your zimbra thresholds determine what goes into spam and discard. ie) Anything scored over 15 is generally discarded. I can't remember Zimbra defaults but I think 5 is the score required before it is put in the junk folder. I use a slightly lower score here.

Hi Jim,

I have already copas your script check_rejected_spam.pl and run it, the output like below:

Code: Select all

# ./check_rejected_spam.pl --spam --rules
user is @ rules[1] ham[0] spam[1] discard[0]

Total counts: 0 Spam Email: 0

# ./check_rejected_spam.pl --discard --rules
user is @ rules[1] ham[0] spam[0] discard[1]

Total counts: 0 Discarded Email: 0
It looks like there is no response, and actually there is content in the zimbra.log file
or is this due to zimbraAmavisLogLevel: 2 ?

Hi Untung,

Probably. You would need to bump up the level or update the parser for the information at level 2 in your logs. At the top of the program, I have this:

Code: Select all

# Zimbra Assumptions:
# Amavis at level 3 logging to see spam_scan lines in /var/log/zimbra.log to parse:
#   % zmprov ms `zmhostname` zimbraAmavisLogLevel 3
#   % zmantispamctl restart
I run log level 3 and it works here. If you have spam-tag, spam_scan, etc in the log, it is probably just an adjustment of the RE to parse it correctly for level 2 logging which probably lacks a field or 2 would be my guess at level 2. My comments say that spam_scan is available for level 3 so you could be missing a complete line in the logs too. Searching for '(spam_scan|spam-tag)' would probably alert you to what is available at level 2.

Jim
