[Mailman-Users] Trouble with some messages being scrubbed

Thanks for confirming Mark. I had read that this was a possible bug - so good to know that an upgrade/new install will likely cure it.

Would the workaround you describe involve setting:

convert_html_to_plaintext = 1
filter_mime_types = [add html/text]

One other question about upgrade/new install - I have read that upgrading an existing installation is rather difficult and might involve downtime, so the preferred method is to bring up a new server and move the lists over.  Is that correct?

Thanks again.

This is a bug in your 2.1.5 version, long since fixed.

This is a scrubber issue. It is independent of content filtering except
in that if you filtered the text/html part out of the
multipart/alternative part leaving only the text/plain part, it would
probably appear OK in the archive.

Because it doesn't exist in 2.1.5, and if it were set in your case, it
would just break individual messages and mime digests as well as
archives and plain digests.

>Mailman 2.1.5.

If you are saying that this happens to individual messages and not to
just plain digests and archives, then this is not 'standard' 2.1.5,
and somehow Scrubber has been inserted into GLOBAL_PIPELINE either in
Defaults.py or mm_cfg.py or in a pipeline attribute of the list.

The real solution is to upgrade to a more recent Mailman that doesn't
have this Scrubber bug.
