When using task managers like Trello and MeisterTask, you get private email adresses that are used for importing new task items via email. I often use this feature by forwarding important emails that i want to import as tasks in these systems. However, Mailspring refuses to find these private adresses automatically when typing in the To-field, even though they been used before and are added to my Gmail contacts (Gmail finds them just fine when using their webmail). I suspect that Mailspring somehow flags them as spam addresses because they are long and randomized in nature. (I cannot find them in Mailsprings contact manger either.)
I would like to be able to manually whitelist these addresses since they are a very important part of my workflow. I want them to appear automatically when typing in the To-field.
