I receive messages that are classified as spam by k9 even though they are not.
How can I change this behavior?
K9 does not have any filtering support (spam or otherwise) so if a message is classified as spam that’s happening elsewhere - likely by your mail service provider. you will need to log into their webmail interface and see if it has the concept of reporting a message that is incorrectly tagged.
Thanks for your feedback
I will look in this direction
