Thank you. Adding additional field "choose recipient" with value "-" is fixing it, indeed.
However I have to abandon your multirecipient field at all, unfortunatelly, as it not fit into my needs. So I have to a little suggestion for future versions.
Below require completely new way of handling miltiple recipients.
As for your simple example:
"contact Bob" -> bob@mail
"contact John" -> john@mail
etc. your miltiple recipient form is enough,
but for more advanced selection like:
"contact admin" -> admin1@mail, admin2@mail
"contact tech support" -> technician1@mail, technician2@mail, technician3@mail
"contact webmaster" -> webmaster@mail
your way of handling it fail, unfortunatelly.
So my sugestion for better future version is to allow multiple recipients for each selection.
Maybe get the recipients from value for each selection?…
"choose recipient|-"
"contact admin|mail1,mail2,mail3"
etc. This will be probably more intuitive than assigning each selection to the following addresses from the list of recipients in separate settings.

One more suggestion – not related to above – "auto confirmation".
Usually auto confirmation is "blablabla, thank you, this is auto confirmation, do not reply". This is indeed usually mail that we do not want to receive a reply for it. So having this in mind there should be no "reply-to" header in this auto confirmation mail, in my opinion.
