I am a big fan and follower of Thunderbird as user.
I use message filters extensively.
It would be good if we can modify the filter conditions in one filter with if and else conditions for each parameter
For example -
I have a filter called IOCL
One condition is if this mail is from @iocl.com then move it to folder named IOCL
then if the mail is coming from @iocl and has the subject contains payment advice forward it to accounts@abc.com
and also the first filter applies
and then if the mail subject is saying no contact then delete it
and so on......
currently in the filter conditions selected we have all the outcome is applied to all parameters
