[xymon] smtp/smtps tests against postfix generate errors on server

[White, Bruce]

You can change what Xymon sends during an smtp test by editing the
<install dir>/etc/bb-services file.

The test is in netservices.c.  You could try patching in a HELO before
the
MAIL command.  Or check postfix's main.cf for reject_unauth_pipelining
directive.  Not sure what removing it might result in for everything
else.
 The "feature" of logging this for every occurrence appears to have been
introduced in 2.6.
