Custom email sending to BCC

[jmestep]

I'm sending emails via custom code and I can get everything to pick up besides the Bcc address.
I've tried
template.BCCList = "xxx@xx.com";
template.AddBccAddress("BCCList");---- I didn't have that in at first and tried to add it to see if it would help.
Can anyone tell what I'm doing wrong?
Even if I put something into the Bcc field in the admin for that template, it doesn't send a Bcc.

This is Able 707


Thanks
