I send mail to spamc using both
smtpd_milters=unix:/spamass/spamass.sock,
unix:/var/run/opendkim/opendkim.sock
and non-smtp mail with
non_smtpd_milters=unix:/spamass/spamass.sock,
unix:/var/run/opendkim/opendkim.sock
in my postfix config. Now local mail, the 'non_smtpd_milter'
directive, doesn't work for me. The people on the postfix mailinglist
suspected this to be a spamassassin issue. What I see is that there
are no headers at all appended to mails coming from the localhost
(i.e. mails from a contact form running on a website on the same
server). The DKIM headers, that are appended through the same
non_smtpd miltering however, are appended which leads me to believe
that maybe spamassassin is ignoring local mail.
Could that be the case?
Sorry, already found out. I use spamass-milter
(https://linux.die.net/man/1/spamass-milter) which, out of the box,
doesn't offer mails from 127.0.0.1 to spamassassin at all.
what do you gain at that level from a milter?
you can't reject without becoming a backscatter and making the problem
bigger for the world after you received a message on the MX
don't accept junk at all instead deal with it later
Sorry, I have no idea what you mean by 'backscatter' or 'making the
problem bigger for the world'. The intention is as follows: Contact
forms get a lot of bots filling them. You can setup a Google captcha for
this, but that would bring Google into your site, training their
selfdriving cars for free, stealing your privacy and annoying a
legitimate user with random bicycle pictures.
So I setup a 'catch' e-mail address that the contactform sends its mail
to. That e-mail address has a VERY low max spamscore attached, as to not
set the score too low for the regular e-mail address. The only further
thing the contact-catch address does it send every e-mail right over to
the regular e-mail address, except for the spam-flagged ones since they
never make it to sieve (that does the forwarding) because they are first
put into the spamfolder right away.
Problem is the mail scores really low, probably because its local?
