Formit CCs can't see each other

I've got a to, some CCs and a BCC setup with the email hook on formIt. The problem is that the CCs are acting like BCCs, so the CC recipients can't see each other.

I've tried sending an email like that from the mail account to make sure it's not the mail server doing that, but those CCs arrived fine.

I'm using FormIt 2.2.0 on MODX Revolution 2.2.9-pl

Any idea what's going on?

Can you post your Formit call?

try to &emailto=`mail1,mail2,mail3`

I ended up using TO for all instead of having any addresses on CC
