The issue is that Mailman changes the content of the mail, hence
breaking the DKIM/DMARC chain. This anti-spoofing measure wants to see
an unaltered mail the whole line through, it can check this using
specific digital signatures. The other changes are related to this,
having Mailman change the subject and add a footer also breaks the
chain. Not adhering to this anti-spoofing measure means mail from this
mailing list has a bigger chance of getting bounced or rejected by other
mail servers with a strict anti-spoofing policy.
And another change I had to make was that I had
to disable the automatic
conversion of HTML mails to plain text. I really don't like having to do
this but if this prevents users getting disabled or even getting
unsubscribed and allows them to receive mail without it getting bounced then
so be it.
I don't follow the logic here (probably my own ignorance), so
could you explain ?
Here anything that is pure HTML is simply deleted
before I even
try to read it, unless there is a good reason to look into it.
One such reason may be the LA* prefix, which now won't be there...
LAU didn't send HTML mail because it was converted to plain text. Now it
does and because the [LAU] prefix was removed you will have to use a
different filtering rule unfortunately to filter out the LAU mail. Some
examples were already sent to the list. I'm using Thunderbird myself and
I'm filtering on "From, To, CC or BCC contains
linux-audio-user(a)lists.linuxaudio.org"quot;. Hope this helps.
So I guess I'll be missing some of the future LA*
content :-(
Hope not!
Ciao,
