   For those that may actually want to try MailScanner on S10 (and use the 
Sun versions of the tools), I have attached a manifest and method that can 
be used with MailScanner (maybe Julian will be interested in putting them 
in the contrib space).

   The scripts and instructions expect that the manifest and method will 
reside in the directory /etc/MailScanner/smf.  The method assumes 
MailScanner to reside in /opt/MailScanner.  You will need to update the 
manifest (the .xml file) if you put the method elsewhere, and tne method 
(the non-.xml file) if MailScanner is elsewhere.

   Note, that putting all the MailScanner config files in /etc allows for a 
single install of MailScanner should MailScanner be used in multiple 
Solaris zones.

   To change the manifest for Sendmail to the new manifest, simply do:

     # svcadm disable network/smtp
     # svccfg -s network/smtp
     svc:/network/smtp> import /etc/MailScanner/smf/ms-smtp-sendmail.xml
     svc:/network/smtp> quit
     # svcadm enable network/smtp

   To go back to the original Sun manifest, just change the "import" line 
to:

     svc:/network/smtp> import /var/svc/manifest/network/smtp-sendmail.xml
