Since Sat Feb 23 19:59:15 (GMT+11), all mail from this list is ending up in
my system's spam quarantine because dmo's anti-spam software is adding broken
headers to outgoing mail.
this is what i'm getting in the quarantined messages:
X-Amavis-Alert: BAD HEADER SECTION, Improper folded header field made up
entirely of whitespace (char 20 hex): X-Spam_report: ...that system
for details. Content previ[...]
caused by headers like these added by dom's anti-spam:
X-Spam_report: Spam detection software, running on the system "deb-multimedia.org",
has NOT identified this incoming email as spam. The original
message has been attached to this so you can view it or label
similar future email. If you have any questions, see
the administrator of that system for details.

That's a single header, and it's broken. Multi-line headers are fine but Mail
headers CAN NOT contain lines consisting solely of spaces. Please fix - make
it use a "." or something if you insist on adding this junk to outbound mail
(not necessary. spam checking is for the receiving system to do, and there's
no way that any sane sysadmin ever sets up their mail server to trust the
sender's spam report header. The mailing-list software should strip these
headers before re-sending).
