Notification mail header "Precedence" should be configurable

[i.bardarov@…]

I want to use Trac to notify a mailing list of ticket change.

Every time when Trac send email I got this error/success in the mail log:

delivery 1118: success: Precedence:_junk_-_message_ignored/did_0+0+1/

To bypass this we have to comment in notification.py

headers['Precedence'] = 'bulk'

It should be great if you can include this as a config option in feature version.

Thanks

An improved notification system is scheduled for 0.13.

Note that disabling this header is a bad workaround that may lead to other issues, such as the ones for which these headers have been initially introduced. I'm not sure Trac should send 'limited' emails to circumvent issues in other software…

I have tested replacing

headers['Precedence'] = 'bulk'

with

headers['Precedence'] = 'list'

and the mail is correctly delivered. So instead of my previous patch in #8609 I suggest to set precedence header to list.

I suggest to change milestone from 0.13 to 0.11.6 too

+1 for making this configurable.
