OK, i upgraded amavisd from 2.5.4 to 2.6.0, installed Mail::DKIM and
enabled dkim verification ... signing is next step.
I can see, in my logs, entries like:
May 20 18:35:14 correio amavis[14826]: (14826-06) dkim: VALID
MailFrom+Sender+Author signature by [EMAIL PROTECTED], From:
<[EMAIL PROTECTED]>, a=rsa-sha1, c=nofws, s=s1024, d=yahoo.com.br
May 20 18:37:53 correio amavis[14826]: (14826-08) dkim: FAILED
MailFrom+Sender+Author signature by [EMAIL PROTECTED], From:
<[EMAIL PROTECTED]>, a=rsa-sha1, c=nofws, s=s1024,
d=yahoo.com.br, fail (message has been altered)
This second one, which got dkim FAILED really came from yahoo.com
servers, as i checked on my logs.
May 20 18:37:49 correio policyd: rcpt=14, whitelist_dnsname=update,
host=98.136.44.52 (n56.bullet.mail.sp1.yahoo.com),
[EMAIL PROTECTED], [EMAIL PROTECTED], size=0
Anyway, even this dkim FAILED is getting the 'Passed CLEAN' status
and being delivered.
i checked 50_scores.cf and seems no rule at all punishes failed dkim
verifications.
maybe i got it wrong ... but what's all DKIM about if nothing
punishes a failed dkim verification ?? Please help me understand that :)
Thanks !
