Not likely. The mails all came from a dynamic ip, so it's very unlikely
that this is a regular server (German T-Com is disconnecting every 24h AND
issuing different ip addresses every time on reconnect):
p549B18A2.dip0.t-ipconnect.de
84.155.24.162
The usual time email is kept in the queue until it is discarded as
undeliverable is only a few days (Postfix has a default of 5 days). No, it
is likely an experiment gone bad. Otherwise the mails wouldn't have come
in such a batch all at once.
It isn't simple to track it. Let me see the received headers of the
"Undelivered Message" in reverse order (ie, up-down):
Received: from lists4.suse.de (localhost [127.0.0.1])
by lists4.suse.de (Postfix) with SMTP id E458870811;
Mon, 1 Jan 2007 11:47:39 +0000 (GMT)
Received: from lists4.suse.de (lists4.suse.de [195.135.221.135])
by mailin.webmailer.de (8.13.7/8.13.7) with ESMTP id l01C0UMi005945

I don't quite see why mail to growngizmo.de end at mailin.webmailer.de,
because "host" says:
cer@nimrodel:~> host growngizmo.de
growngizmo.de has address 81.169.145.69
growngizmo.de mail is handled by 10 mailin.rzone.de.
cer@nimrodel:~> host mailin.webmailer.de
mailin.webmailer.de has address 192.67.198.32
mailin.webmailer.de has address 192.67.198.37
mailin.webmailer.de has address 192.67.198.48
mailin.webmailer.de mail is handled by 10 mailin.rzone.de.
Ah, both growngizmo.de and mailin.webmailer.de have mail handled by
mailin.rzone.de.
So we had:
Received: from lists4.suse.de (lists4.suse.de [195.135.221.135])
by mailin.webmailer.de (8.13.7/8.13.7) with ESMTP id l01C0UMi005945
for ; Mon, 1 Jan 2007 13:00:31 +0100 (MET)
So mail arrived at the box on January, but he fetched it Yesterday:
Received: from post.strato.de [192.67.198.2]
by dothangizmo.gk.lan with POP3 (fetchmail-6.3.2)
for <4suse%growngizmo.de@localhost> (single-drop); Sat, 03 Mar 2007 01:42:57 +0100 (CET)
And the next step is local, but the user name has changed (typical with
postfix) to 4suse%growngizmo.de@localhost:
Received: from dothangizmo.gk.lan (localhost [IPv6:::1])
by dothangizmo.gk.lan (Postfix) with ESMTP id CB14D6319
for <4suse%growngizmo.de@localhost>; Sat, 3 Mar 2007 01:42:57 +0100 (CET)
X-Envelope-From:
X-Envelope-To:
X-Delivery-Time: 1167652831
The delivery time is huge. I think the mail was being collected at the ISP
box, and fetched yesterday during the early hours. What happened next I
have difficulty following; the would be received paragraph should be this
one (part 1):
<4suse@growngizmo.de> (expanded from <4suse%growngizmo.de@localhost>): host
mailin.rzone.de[81.169.145.100] said: 550 5.0.0 Dial-Up IP address rejected
(in reply to RCPT TO command)
Maybe his postfix tried to send to "4suse@growngizmo.de", instead of
taking it locally, as was intended. He is "growngizmo.de" (I think), but
his mail is handled by mailin.rzone.de, which refused his client being
dynamic... so finally, postfix, not knowing how to send to
"4suse@growngizmo.de" bounces back to us.
Does it sound reasonable?
If I see any more of the crap I could try to get him on the phone, if the
phonebook entry is valid.
Good luck :-)
