Emails bounce back: 550 Messages should have one or no To headers, not 2

I’m setting up Buddypress and WP Mail SMTP and when I register a new account the activation email keeps bouncing back to the sender address. I get the following error:

SMTP error from remote mail server after end of data:
550 Messages should have one or no To headers, not 2.

The “To” address IS in the “To” field TWICE but I can’t figure out why. I assume that’s why it’s bouncing back. I don’t have any other registration or membership plugins running right now. I am using WP SMTP MAIL to enable me to use Gmail as my sender. It DOES send the test email properly, and only to one address in the “To” field. When I disable the WP Mail SMTP plugin the activation email actually DOES send, but it comes from wordpress@mydomain.ca, which I don’t understand.

Any advice on this?
