Hi List,
I see the useful X-Spam-Relays-External pseudo header but what I'd
really like to be able to specifically check is the Last External
header as DNSBL rules are able to do with -lastexternal.
Is there a X-Spam-Relays-Last-External option that I'm missing, and
if not would it be possible to implement such a feature or perhaps
someone can suggest a workaround method?
For example, I'd like to be able to do something like this against
only the last external Received header:
header __RCVD_FROM_SOMEISP X-Spam-Relays-Last-External =~ /someisp\.com/i
Thanks
Example from 20_dynrdns.cf
# Note the '^[^\]]+ ' stanza: this ensures that we only match spamware
# connecting to a internal relay; if a mail came from a dynamic addr but
# was relayed through their smarthost, that's fine.
...
header __LAST_EXTERNAL_RELAY_NO_AUTH X-Spam-Relays-External =~ /^[^\]]+ auth= /
To prevent further questions..
header __RCVD_FROM_SOMEISP X-Spam-Relays-External =~ /^[^\]]+ rdns=[^
]+\.someisp\.com /
As you see, all the relays are enclosed in [ ..relay1.. ] [ ..relay2.. ] ...
Thus the stanza will not look further than first ].
Brilliant - thank you very much. Works perfectly.
