Curious e-mails from yucom.be

[Steve Greenland <stevegr@debian.org>]

Today I received several e-mails that were near duplicates of
interactions with the BTS last sunday, both from me and from others.
The originals had headers like this (I've trimmed the extraneous stuff):


Received: from gecko by master.debian.org with local (Exim 3.12 1 (Debian))
        id 14rP8Z-0003SF-00; Sun, 22 Apr 2001 14:03:11 -0500

          (code B ref 79711); Sun, 22 Apr 2001 19:03:08 GMT

The duplicate has:

Note that the message id is the same; it just went to "yucom.be", who
held it for a 4 days and then respewed it back to me at master. Any
ideas what's going on? Or how I can make it stop?

Thanks,
Steve

PS Notice that I refrained from making any snide comments about
crappy Microsoft mail servers.
