Format of email list in "forward to" for email forwarding

[mericson]

How do I format the email list in the "forward to" text box? Are email addresses newline separated, comma separated, space separated? The forwarding isn't working for multiple emails and I suspect it is the format I'm using for the list of emails.

It's 2019 now and yet no one answered.

I made a test myself and separation by new line works, like so:

email1@domain1.tld
email2@domain2.tld
