Yes, and there's a link at the bottom of that page to the postfix.org
add-on page which specifically warns against MailScanner.
What would be the advantage to switching to something like
amavisd-new?
The advantage to something that uses the SMTP Proxy interface or the
Milter interface is that you can trust that it won't be broken without
warning or documentation in a future Postfix release. Apart from the
risk that it relies on Postfix not changing queue structures and
behaviors which are explicitly unsupported and subject to change,
MailScanner works directly with the Postfix queue in a way that Wietse
has been saying for years is already not safe. I haven't analyzed the
Postfix queue-handling code (life is too short...) but I trust his
judgment of safety in working with the Postfix queue over that of anyone
who didn't write that code. The MailScanner argument (essentially that
what they do doesn't break enough to notice) is entirely unpersuasive.
