[Exim] Sendmail senging 220 ******0**********...

I'm connecting to a Sendmail system and when you connect all it sends at
first is:

220
******0**********************************2*0**********2*0*********2******200
***0********0*00 *****

Is this supposed to signify something?

As soon as you do a HELO... It responds like you would expect, but it always
starts out with the above.

Just curious if anyone knows.
