Allow inbox filtering to forward an email to another address rather than move it to a folder

[Ssieth]

Or better, yet, to do both?

This is becoming a big issue for me and would love any help with this...

Hey @Ssieth , there are ongoing discussions to extend inbox rules to be able to do more, though I doubt mail forwarding would be addressed in the super near future. Adding labels to inbox rules is however planned.

Add another Tutanota user wanting the choice between folders and external email addresses for sorting rules.
