As per subject. This is hard to trace for me because
they are put in a
"spam" folder in the webmail interface which I hardly ever use.
One of thes is e.g: linux-audio-user(a)lists.linuxaudio.org
ISP says this is correctly marked as spam because it doesn't have
"standard features routing / resolution / related to domain" (I'm
translating this from Italian. And in a further email that they check
"correct routing of the sender in relation to DNS domain and not only
reverse etc." (again my translation).
Any mail-admin guru have an idea about this?
Not a mail admin guru, but it seems linuxaudio.org does not
have an SPF record. See:
http://www.openspf.org/
It also doesn't use DKIM:
http://www.dkim.org/
Personally I find that DKIM is a far less reliable spam/non-spam
indicator than SPF.
Of course it would help if they simply had an option
to whitelist
addresses ("this is not spam") or something similar which they seem not
to have.
It would also help if you get the ISP to specifically
point to which technology they expect.
