That's fine with us.  We are proud of Mailman 2, it's just that a
decade ago we could clearly see it was reaching the end of the line
for major feature development.

IMO, everybody should definitely update to the most recent version of
Mailman 2 which is available from Launchpad via the bzr VCS (you can
also download a tar.gz or maybe a .zip) as well as many distros'
package repositories (if not the very most recent, something much
better than 2.1.12 or 2.1.15).

There have been *many* improvements since then, including the DMARC
mitigations mentioned elsewhere in this thread that may help address
this problem, but also a number of security issues that affect third
parties (a few cross-site scripting vulnerabilities, for example) have
been addressed.  Staying up to date on Internet-facing software is
just plain good citizenship.

Here.[1]  The answer will be "No" ;-) *but* that will be followed with
(a) various suggestions for workarounds in the stock Mailman from
developers and other users and (b) help with creating specific patches
for sites to maintain for themselves.  (a) is why I suggest here
rather than mailman-developers -- other users are a great resource!

We aren't opposed to folks developing Mailman 2 further, patch by
patch.  We're strict about devoting project resources to Mailman 3.

Footnotes: 
[1]  If it applies to Mailman 3 as well, an RFE on the tracker at
https://gitlab.com/mailman would be appreciated, though.

[Mailman-Users] messages being labeled as spam in the subject line?

Mailman does not do this, unless the list admin sets the subject tag
to something containing "spam".

 > Is this a mailman setting that can be changed

No.  Mailman does have optional (quite primitive) spam filtering built
in, all it does if it catches something spammy is hold it or discard
it, depending on settings.  Stock Mailman will not edit the message
just because it's spammy.  This filtering is off by default IIRC,
because we recommend using it only as a last resort.  Filtering should
be done in the MTA, which has access to much more effective filtering
options.

 > or is it a setting either with the mailman hosting provider?

This should be the responsibility of the final recipient, not the
Mailman host.  Unfortunately the Mailman host MTA cannot automatically
tell the difference between a mailing list post and other local mail.
Worse, it may not be able to communicate this to a filter.

If it turns out to be the Mailman host, the MTA needs to be
reconfigured.  In the simplest case, the MTA just gets a list of list
addresses and sends mail for them to Mailman after doing its standard
processing including spam filtering.  In this case, you need to do a
lot of reconfiguring and I can't get into it here.

In most cases, every action taken by the MTA can be configured
conditional on the address.  It is a very bad idea to disable
spam-checking for a mailing list.  What needs to be done is to
configure the spam-checker to *not* alter the Subject, but only for
Mailman posts.  Of course they could disable marking the Subject with
"spam" for all mail, but that would surely get very strong pushback
from the host admin.  On the other hand, if you're sure enough that
something is spam to edit the Subject, you really shouldn't be
distributing it to a mailing list at all.

This is going to be specific to the MTA and to the spam checker.

I believe this is from random members replying to messages that were tagged as 
spam by the users' ISP/Mail software (eg false positives and/or broken spam 
filter settings).

Is this a mailman setting that can be changed or is it a setting either 
with the mailman hosting provider?



Both Steve and Robert have given relevant replies, but to summarize:

It's not Mailman.

The two possibilities that come to mind are:

- The incoming MTA on the Mailman host has tagged the message as spam 
but delivered it to Mailman anyway.


- A user is replying to a message that her MTA tagged as spam without 
removing the spam tag from the subject.


For the second case, I'm sometimes guilty of this myself. My MTA (via 
MailScanner) tags subjects with {spam} or {disarmed} and I sometimes 
reply to such messages without removing the tag.
