Its basic task is to provide automatic tagging each time new mail is registered with
notmuch. In a classic setup, you might call it after
notmuch new in an offlineimap post sync hook.
It can do basic thing such as adding tags based on email headers or maildir folders, handling killed threads and spam.
In move mode, afew will move mails between maildir folders according to configurable rules that can contain arbitrary notmuch queries to match against any searchable attributes.
First install the requirements:
sudo apt-get install notmuch python3-notmuch
Finally install the program:
pip3 install afew
To tag new emails use:
afew -v --tag --new
