Interesting idea, but, having thought about it, I don't it's the case.
I sent the same emails to two different addresses - one Domino and one not. I then downloaded the emails in to two different accounts in Thunderbird - one connecting to Domino and one not. Only the Domino account showed the issue and neither account had the option to fetch headers enabled.
