Multiple DKIM signature log messages

This is a bit weird, the same message reported 4 DKIM verifications
with identical details:
2009-10-27 21:30:58 ******-******-** DKIM: d=facebookmail.com s=q1-2009b c=relaxed/relaxed a=rsa-sha1 i=@... t=********** [verification succeeded]
2009-10-27 21:30:58 ******-******-** DKIM: d=facebookmail.com s=q1-2009b c=relaxed/relaxed a=rsa-sha1 i=@... t=********** [verification succeeded]
2009-10-27 21:30:58 ******-******-** DKIM: d=facebookmail.com s=q1-2009b c=relaxed/relaxed a=rsa-sha1 i=@... t=********** [verification succeeded]
2009-10-27 21:30:58 ******-******-** DKIM: d=facebookmail.com s=q1-2009b c=relaxed/relaxed a=rsa-sha1 i=@... t=********** [verification succeeded]

I doubt the message was actually signed multiple times, as other
email from the same domain only outputs one signature verification,
but it's not impossible...

If you can still retrieve the email source, send it over. It COULD be a
bug, but at this point I just suspect it had 4 DKIM-Signature: headers. :)
