"RDNS_DYNAMIC3" score - SpamAssassin

[Guest]

[opsystem]

Hello all,

I'm on EFW 3.3.0 with SMTP proxy + antispam enabled. Incoming messages get obviously scanned like this:

Code:

X-Spam-Status: No, score=3.529 tagged_above=0 required=4 tests=[
........

RDNS_DYNAMIC3=1.5, 

.......]
	autolearn=no

Now I want to change that RDNS_DYNAMIC3=1.5 (I don't want clients to be discriminated if they send emails from dynamic IPs). But I can't figure out how and where to edit it. I've tried to add:

Code:

score RDNS_DYNAMIC 0
score RDNS_DYNAMIC3 0

in /etc/spamd/local.cf.tmpl, but it has no effects. I know that the main SA files are in /var/lib/spamassassin/3.003002/updates_spamassassin_org but I doubt that's the right place for customizations.

Any clues?
Thanks for helping me

Ok, this seems working as a workaround:

/var/lib/spamassassin/3.003002/spamassassin_emaillab_jp/20_head_tests.cf

Code:

meta	 RDNS_DYNAMIC3	( __LAST_UNTRUSTED_RELAY_NO_AUTH && !RDNS_DYNAMIC && !__RDNS_DYNAMIC_BL && !__RDNS_STATIC2 && !__RDNS_STATIC && __RDNS_DYNAMIC_S25R )
describe RDNS_DYNAMIC3	Delivered to trusted network by host with dynamic-looking rDNS
score	 RDNS_DYNAMIC3	0.0

This seems to survive reboots, howerver I'm not convinced at all!

Hi,

is better if you revert back the modification, you will lost it in case of Endian updates spamassassin.
If you want to add custom scores, please add it inside the file /var/efw/spamassassin/localcf.custom.tmpl (create it if doesn't exist), after placing your custom scores you should restart the smtp proxy with the command:
jobcontrol restart smtpscan --force

Hi Daniele, thanks for your answer, I know that I’ll loose my changes when I upgrade, but on EFW 3.3 I’ve never found the right place for the SA custom file.

• There’s no updated documentation
• Using any of these files has no effects at all:
  
  
  • /var/efw/spamassassin/localcf.custom.tmpl
  • /var/efw/spamassassin/local.cf.tmpl
  • /var/efw/smtpscan/localcf.custom.tmpl
  
  

So they are not used.

Honestly I’ve no time to try every combination of paths and filenames, nor to debug the SA loading routines, so I hope that someone will post the right solution.

As a side note, these are the files that are loaded by SA:

Code:

spamassassin -D --lint 2>&1 | grep using
Jan  8 23:19:40.808 [4857] dbg: ignore: using a test message to lint rules
Jan  8 23:19:40.808 [4857] dbg: config: using "/etc/spamassassin" for site rules pre files
Jan  8 23:19:40.810 [4857] dbg: config: using "/var/lib/spamassassin/3.003002" for sys rules pre files
Jan  8 23:19:40.810 [4857] dbg: config: using "/var/lib/spamassassin/3.003002" for default rules dir
Jan  8 23:19:40.811 [4857] dbg: config: using "/etc/spamassassin" for site rules dir
Jan  8 23:19:40.919 [4857] dbg: config: using "/var/lib/spamassassin/3.003002/spamassassin_emaillab_jp/20_body_tests.cf" for included file
Jan  8 23:19:40.922 [4857] dbg: config: using "/var/lib/spamassassin/3.003002/spamassassin_emaillab_jp/20_head_tests.cf" for included file

[...]

Jan  8 23:19:41.507 [4857] dbg: config: using "/var/lib/spamassassin/3.003002/updates_spamassassin_org/local.cf" for included file
Jan  8 23:19:41.508 [4857] dbg: config: using "/var/lib/spamassassin/3.003002/updates_spamassassin_org/regression_tests.cf" for included file

Ok, here is one “almost” solution I’ve found:

1. Open /etc/spamassassin/local.cf.tmpl

2. Change:

Code:

#include “/var/efw/smtpscan/local_cf.custom.tmpl”

to:

Code:

include /var/efw/smtpscan/local_cf.custom.tmpl

(quotes must be removed)

Now you can create the /var/efw/smtpscan/local_cf.custom.tmpl file and put your customization in there. This seems to be effective on emaillab_jp scores too.

Note: I’m not sure that the local.cf.tmpl edit will persist upon the EFW upgrade

Cheers
