EDIT - I just realized I misinterpreted the settings and this currently works as I would expect, sorry for the interruption.
Test mail works fine and daily digest works fine. But I'm not getting mail when others posted information in the topic which I created. I enabled Follow Topic which i create and and reply to. Kindly guide me how to use this feature in NodeBB.
Requirement : Need to get email notification when people post the information in the Topic i created and replied to my post
Sorry to revive this, but I also wholeheartedly agree this is a required feature, potentially with @a_5mith 's suggestion implemented for busier forums.
