Lines 1225 & 1232 pass an array into the mail() function as the first parameter, but the function expects a string.

Surprised this has gone unnoticed.

(I’d prefer to use “smtp” protocol or “sendmail”, but they’re not working for me yet.)

Follow-up… seems as though $this->_recipients is an array until a recipient is added, at least when using “mail” as the protocol.

Not a bug.
