Hi All,
This may be a weird one, and may be completely OT. If the latter:
Feel free to tell me to bugger off :)
System is FreeBSD 8.2, running ipfilter and
postfix-current-2.9.20111119,4.
Occasionally I see something like this from ipfilter in
/var/log/messages:
bge1 @0:24 b <my_outside_ip>,25 -> 89.73.201.168,36545 PR tcp len
20 40 -AR OUT
Looking in /var/log/maillog...

unknown[89.73.201.168]
This particular one occurred seven times in a row, in quick
succession.
I've searched on this *fairly* seriously and come up with nothing.
Anybody got any idea what this is?
Thanks,
Jim
