smtp 421 code

Hi,

we are running
ZMailer smtp (2.99.55 #1: Mon Nov  5 11:32:39 ART 2001)
but there is nothing similar in the ChangeLog.

When yahoo returns 421 the delivery is attempted
once a second 5 or 10 times until it stops
and restarts again a little later.

(xxx@yahoo.com is an alias for a local user)

I think is not right...

may be it is because Pipelining is in efect and
the 421 code is not read because of the pending answers?

TIA
