Re: virus issues



I'm not sure why the ICW adds those settings under the relay restrictions -
that may be better asked in the SBS newsgroups. I know it isn't the default
for regular Exchange (Standard or Enterprise), so it may be specific to SBS.
As far as the authenticated relay, it is indeed on by default. My
recommendation was that if you do not support any IMAP or POP3 clients it
should be disabled (unchecked).

As far as your second question about Anonymous access, you have to leave it
on. That controls how other mail servers are able to connect to you and
send mail to you. If you disable anonymous, you'll find that you stop
receiving e-mail :-) SMTP conversations (unless specifically set up
otherwise) are all anonymous. When you send an e-mail to another domain,
your server does the same thing (establishes an anonymous session).
