I've tried to filter any message that contains "Re:" in the subject.

It always seems to ALSO filter words that contain "re" .

Based on my travails I'm not sure that it is even looking at the colon.

I've found no suggestions from others.

When receiving replies from a discussion group it would be nice to dump them all in a folder as read and then maybe later read those that i might care about. See those words: " receive" "read" and "care" guess what my filter does when kit sees those words in a subject line. <G>

Alter your filter Subject - starts with - Re: 'Re: ' - Re: followed by a single space

I think I followed your suggestion., It did not work.

I've tried begins with

and used: 

-re: Re: -Re:

none of these work.

If you want to put in exactly what you want me to copy and paste I can try again. The version of TB is same but I'm running Win8.

try Re: without the space after it. Works in my test.


Before folder contains several messages. One subject line is 'Re: Answer' Filter name [Any] Subject - begins with - Re: (no space after the colon) Do action - Tag - Test Result - 'Re: Answer' is only message tagged 'Test'


I created a new tag 'Test' to check filters - if the message gets tagged then the filter works. I can then change the Action to whatever.

FYI: Once you tag a message with a filter, you cannot use a filter to remove or change it. All you can do is add additional tags. To manually remove all tags, at once, highlight the message in the thread pane and press '0' (zero).
