The Ironport machine is SA in disguise. So you effectively have two copies
of SA in series. You porbably understand this, but I'm just mentioning it
to be sure.
SA begins scanning a message by first removing any previous markup it may
have inserted. In this case, the second SA will remove all of the markup
beginning with X-Spam that the Ironport SA installed.
You can't keep SA from doing this. But you may be able to use procmail or
some other integration tool to change the Ironport X-Spam-xxx headers to
X-Ironport-Spam-xxx headers or the like. These won't be "X-Spam" headers,
so they won't get stripped in the second SA instance.

Subject: Re: SpamAssassin removing X-Spam-Flag header
SpamAssassin is configured to add the header when it's spam and not when
it's ham.
you can change that
add this
add_header all Flag _YESNOCAPS_
and it will keep the header in both cases.

the
Ironport to add the "X-Spam-Flag: YES" header to messages that it
determines
to be spam, as we have already trained our user population to look for
that
header to redirect their spam messages to a separate folder.
After doing some tests, however, I discovered a problem. It looks like
SpamAssassin removes that header if it does not determine that the
message
is spam. Is there a way to configure SpamAssassin to leave that header
alone if it already exists?
We are using SpamAssassin 3.1.8, which is launched via spampd, the spam
proxy daemon, which gets the messages delivered to it from postfix.
Thanks,
