Hi there,

Could anyone offer some tips about implementing an HTML free mailing list?

Many thanks,

Hi,

Do you want to reject html mails ?

Or alter mail content to convert html content to text ?

Hi,

have a look at https://github.com/awerner/pymime - that's what we use
at The Document Foundation for filtering.

Reject with a message saying please re-send as plain text. :-)

That and Henne's spam filter header suggestion seems a bit overkill
for my liking.

I think I pretty much have what I want with: http://ix.io/6RT

Have I missed anything?

There are a lot of things that can be multipart/alternative and
multipart/related in a mail. And especially people with very broken
client setups tend to not send mime-formatted text. It has proven to be
not very reliable for us...

On my testing Gmail as a MUA sends emails with patches for example
with multipart/mixed. Same goes for mutt MUA.
multipart/alternative for HTML in gmail
multipart/related when using emojii in gmail


This is for the "elitist" http://suckless.org/community group and I
like to think testing with mutt/gmail covered the bases here...

We serve over 130 lists with over 32K subscribers and around 2K mails a
day. I guess there are nearly as many MUA/MTA/Config combinations ;-)

If you run a small amount of list with a specific set of people
subscribed filtering on multipart/* can work. It all depends on your
subscribers...

In control/access for the list add

	allow ^Content-Type: text/plain
	moderate

There may be others you want to allow and you may want to change moderate to deny.
Or you may want to specifically deny multipart and text/html

There may be other ways... that's how I've done it.

Very true.

Beware of things such as signed mail, which are usually multipart.
