Not a bug emails to notify throws error with two addresses

First email works perfectly, second throws an error.


I tried removing the space between the addresses, to no avail, but I guess that was to be expected.



Both addresses are valid and I've sent and received emails from them.

Thanks.

This is not core functionality. It must be from an add-on.
