Hello list,
I think spamd users would like to try this small utility.
Although its development is in the very beginning it does its job
quite well for me it was written for the case
where a big mass mailer like google is trying to send us mail.
The utility notices such mailers and white lists it by adding its
allowed nets taken through spf queries to the white list. i.e.
it reads output of spamdb, then checks spf records for all greylisted
mails and produces 'whitelist.auto' file which can
then be used with spamd-setup.
it is small, so I put it into attachment.
I see a tiny little problem with this method... sometimes people send
spam from domains whose DNS they control.
See, in the case of spam there is absolutely no silver bullet. Even
with my current setup I get 5-10 spam messages into my personal
accounts + tons of spam to role accounts like postmaster, hostmaster etc....
But at some time I got tired of adding the web-frontedned-mail
-senders-which-never-repeat-mail-from-the-same-ip to the whitelist. So I
wrote this little thingy.
