Subject: SIMS talks to itself?

[SIMS 1.8b8]

I get frequent ORBS tests (I think spammers submit my IPs hoping to annoy
me), but on Wednesday I had an ORBS test that created 2,800 lines in my
SMTP log. Yes a tad excessive, I've asked Alan to take a look and find out
why he keeps testing me.

But amongst the ORBS tests are a whole bunch of conversations between my
SIMS server and itself... it's talking to itself and submitting mail to
itself which itself is accepting, then it's saying goodbye to itself, then
it's getting another connection request from itself and saying HELO to
itself again... Perhaps it's moved into a parallel dimension where there's
another identical SIMS server on the same IP address and the two have
established a relationship, wow!

The relevant part of the ORBS test (all 2,800 lines of the test) is at
http://www.uxn.com/engineering/orbs.txt 193.115.218.8 is my SIMS server
(but that's not an advertised IP, the server is multihomed, it's main IP
which is advertized as the MX is 193.115.218.2)

The funny stuff starts here:

10:40:20 4 SMTP-860([194.178.232.55]) Input Line: HELO
relaytest.orbs.vuurwerk.nl\r
10:40:20 4 SMTP-860(relaytest.orbs.vuurwerk.nl) Looking for

ain't no client of mine.

10:40:21 4 SMTP-860(relaytest.orbs.vuurwerk.nl) Input Line: DATA\r
