This doesn't seem to happen each and every incoming message and I guess
it really doesn't hurt anything however I'm just curious as to what
might be causing it. It appears to have been going on all year so far
but as I said not with every incoming message just from certain domains
it seems.
Any ideas?
It's the dot-dot in that request.
(1) Do you happen to have a spample that does that? If so, could you
upload it to pastebin and post the URL for it here?
(2) What version of SpamAssassin are you running?
See:
https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7156
https://bz.apache.org/SpamAssassin/show_bug.cgi?id=6896
That was converted from a warning to an info, so it looks like your SA
version may be a bit stale.
I don't think we ever pulled the trigger on normalizing ".." ⇒ "." for
URIBL lookups as a URL with a malformed FQDN like that doesn't work in a
browser.

I'm seriously considering getting one of those bright-orange prison
overalls and stencilling PASSENGER on the back. Along with the paper
slippers, I ought to be able to walk right through security.
