The automatic forward from Gmail (or other providers) is very good, but I should have an option to have a label automatically identifying which emails are coming from there rather than to Proton. Right now I had to create a filter that applies a label when the recipient is my personal email; however, this doesn't work all the time. For example in those cases where I'm not in the recipient (eg Bcc or mailing lists), this label is not automatically applied and thus it would be good for Proton to do this automatically for me.

Thanks!
