Thanks Rob, and to all the others -- not few in number -- who wrote on
and off the list with ideas and links.
I have seen some CONNECT attempts in my logs, trying to make contact
with remote mail servers, but had never made the connection myself
between them and the "\x05\x01" entries. It does seem that someone
is looking for open proxies, as all but all of you indicated.
Our website is a simple one, and I have *everything* turned off that
isn't being used. Proxies are completely disabled and I don't allow
the CONNECT verb, among others. It looks like my ( paranoid )
policies are paying off.
Thanks again to all.
