Thunderbird message filters often miss messages on first few runs - Why?

[tankman1989]

I was wondering if anyone else runs into this. I have been creating a lot of filters for Thunderbird as the number of emails I'm getting daily is making it difficult to sort. I have found that VERY often when I create a filter and then run it on the inbox it very often misses a lot of messages. I can run the same filter 3-6 times and each time I see more and more messages disappearing. I can't figure out why or how it can miss so many messages.

An example is this. I select an email from Newegg. I open the email, right click on the "From" and select "create a From filter" and select the destination folder for the message. I probably had over 50 of these emails in my inbox and the first time I ran it the filter moved maybe 5-8 messages. I then ran it again and it moved none. I then highlighted all the messages in the inbox and selected "run filters on selected messages" and it only moved a few more. I then kept running it and finally after 3-4 more runs they were all moved. This happens with any email address and found that 5/5 filters have performed this way with it never finding 100% of the messages.

Does anyone else have any problems with Thunderbird filters? Is there any reason that can be thought of that would cause this? Thanks

I know we are all techs here, but here you are just going to get a lot of speculation or no response at all. This is really an application specific feature kind of question that's more likely to get some decent feedback if posted here.

I noticed that I hadn't selected "Match any of the Following" which meant that the message had to adhere to all the rule I inputed. This still doesn't explain why it was not getting all of them in one running of the filter. I wonder it has anything to do with the massive amount of email it was sorting? Perhaps I hadn't allowed it to finish running, IDK.

Thanks for the suggestion above!

Just speculating here..

But when blocking 'specific' email messages, you may wish to check out the
email source code or the headers before hand. This may give a clue as to
why some get blocked and some don't.
Good Luck!
