I'm not sure I understand--Doesn't postfix report a "mail from" command to the Milter by invoking the xxfi_envfrom callback? As I understand it, that isn't the end-of-message protocol stage. In the control flow diagram (https://www.milter.org/developers/overview#ControlFlow), it seems that when postfix invokes xxfi_eom, then the processing is in the end-of-message protocol stage. So, calling smfi_addheader in xxfi_eom shouldn't be a problem.

I'll turn on verbose logging. Is there any document I need to refer to in order to understand the verbose logging messages? Thanks, Alban
