The mailing list message of my post (i.e. the one that I received back through the list) does contain only one Delivered-To: header - the one I quoted above.
So, does your server not add this header maybe?
Apparently not. And why should it...? At least this isn't anything you can rely on
"Delivered-To" is a fanatsy header and not required by any RFC
I know. At least this was the stage a few years ago, when I was still dealing with those kind of issues. I'm not familiar with later RFCs that may have been published since then.
OTOH I don't see a problem with supporting non-standard headers if they exist. But that should always be a last resort, and a solution for pure RFC-compliant messages should also be provided.
