1233039 - [RFE] include also e-mails already read to the automatical filter

Status: UNCONFIRMED

(Thunderbird :: Filters, enhancement)

Description

[u552782]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

I have created several automatical message filter whith several conditions that move new messages when calling to another folder.


Actual results:

If I have read an e-mail on a mobile device, Thunderbird downloads the e-mail with the flag 'read' via IMAP. Now this e-mail cannot be filtered automatically, but only maniually.


Expected results:

E-mails already read should also be included to the filter, if this is wanted by the user.
It would be nice to add an option to filter also e-mails whith the flag 'read'.

Today we read emails on multiple devices, it is not the 2000s anymore.
One possible solution to apply a filter to already seen emails is to check the box Periodically, every 10 minutes which is very inefficient especially if the folder contains thousands of emails.

This issue really needs to be fixed to avoid using inefficient workarounds. A filter should be applied to all fetched emails, read or unread. It is up to the user to filter out read emails with Status / is / New if they want to.

Apply filter when:
Getting New Mail

should be replaced with

Apply filter when:
Getting Mail

bug 1320832 made mail.imap.filter_on_new the default (true) to filter IMAP messages new to Thunderbird based on high water mark, regardless of read status. To the best of my knowledge that still works, and based on comment 0 this bug should marked a duplicate of 1320832

My filter checks for some content in the subject/from, then tags the emails.

I tried this experiment: I closed Thunderbird and sent myself 2 identical emails from the web, after I received both on my phone (FairEmail app), I opened one of them. When I launched TB, the message I read slipped through without filtering and the unread one was tagged as expected. Setting mail.imap.filter_on_new to true or false had no effect on the process.
