[Mailman-Users] Personalization - How do I explicitly disable Sender field rewrite

[Tim Van Dyne]

I just upgraded to 2.1.9 and it seems that Personalization now re-writes
the "Sender" or "From" field on all recipients' emails to use the
'description' of the list.  I've been unsuccessful in disabling this
unless I delete the description field, but then there would be no
description on the listinfo page.  Is there a quick entry I can put into
mm_cfg.py or modify on one of the other files to disable the Sender/From
rewrite?
 
It seems like defaulting to 'No' for personalization starts out ok.
Then I change it to 'Yes' and it makes the From field:
"list description" <email at address.blah>
 
I want just:
<email at address.blah>

When I change Personalization back to 'No', the effect stays the same.
Now I'm unable to get rid of this From field rewrite unless I make a new
list.

We want Personalization in order to use some variables in the footer,
and of course to remedy some external user spam filtering issues.
But we don't want the Sender/From field to contain the list's
description.
