BCC to Insightly Email does not work

When entering an Insightly address to BCC emails to, the function does not work. Tested and confirmed in a test account. See ticket below.  

 Hi,

I have discovered that emails are not bcc'd into Insightly CRM. Have I done something wrong in settings?

(I send emails from post@freeliving.no)
