This is really strange.
I am using InfoPath 2010. And i have 2 different forms (one test and one i plan to use). I can use submit email functionality from the test form and is sending email also to external address (e.g. gmail). For the real form i have same security settings (full trust) but somehow the email does not arrive at the external addresses. I don't get any error, the email appears in "sent" folder with the gmail & my company address at "to", is received in corporate inbox, but not on the gmail address. If i try to forward it from corporate account to gmail account i still don't receive it (though it appears in sent again).
And this is happening only for the real form, the test one works ok.....the difference is that the real form is more complex, with external receive data connections and was injected with Qdabra rules.
Your help is much appreciated!!!
