I have deployed Spam Assassin between Postfix and Dovecot. It works
except for a weird problem.
I use a custom URI RBL in addition to the default ones. This works with
a test URL in the body of an email message, however with real spam URL's
- which are listed with other URI RBL's - Spam Assassin is scoring on
those and not on the custom one.
Local configuration:
urirhssub URIBL_CUSTOM rbl.myrbl.tld. A 2
Note: I am not sure which of the following is correct but they both work
and don't work and described above.
#body URIBL_CUSTOM eval:check_uridnsbl('URIBL_BLACK_NS')
body URIBL_CUSTOM eval:check_uridnsbl('URIBL_CUSTOM')
describe URIBL_CUSTOM Body contains a URL listed in our URI
RBL
tflags URIBL_CUSTOM net
score URIBL_CUSTOM 5.0
I am not sure what this does so I commented it out.
#reuse URIBL_CUSTOM
The format of the RBL zone records is:
spammyhost.spamdomain.tld.rbl.myrbl.tld
To reiterate - it does work, but not all the time.
Help much appreciated, thanks.
