Error when starting Mailscanner

[Lance Haig]

Hi,

I get the following error when I restart my MS server

sendmail
    (reason: 550 5.1.1 <sendmail at mailhost.redarmour.co.uk>... User unknown)
    (expanded from: sendmail)
-bd

It seems like the sendmail command line is being put into the mail queue 
and sendmail is trying to deliver it.

Has anyone seen this before?

I am running the following

MS 4.56.5
with Sendmail
on SUSE 9.2

Thanks
