“Invalid mailbox syntax”

Hi,

Thank You very much for this plugin. It works fine.
There is only one disadvantage, however it’s rather a cosmetic one:

I have in first step a field [email* email id:email]. After submitting the second step of the form an email should be send to this address but CF7 reclaims: “Invalid mailbox syntax is used.” Formally this is ok, as in second step there isn’t a required field [email*].
However the email is send correctly.

Is there a possibility to use the field [email] typed in first step in the mail responder of the second step without error notification?

Thank You
