Hello, I have a few questions about the mail server administration.
1. How do I properly setup a catch-all email address? I want to catch all email that is not addressed to an existing user.
2. How can I filter emails based on it's message content and have them deleted? When I go to Spam Filter > Custom Rule,I don't see the option to filter a message by it's message content.
3. Lastly, does this product synch up with a spam database and automatically remove known spam?

Under Domain settings\Aliases setup an entry that says "*" for alias and
choose a "Deliver To:". Keep in mind that this way any user name is a valid
one, so spammers sending to otherwise undeliverable e-mail recipients will
be able deliver the messages.

Don't know. Unfortunately the Kerio manual is not very good on the subject
of the Sieve language.
I don't think you can create a Sieve rule to match on content.
I have a pretty large set of rules, which I switched to modify as a script
a long time ago (since I found it to be much more convenient), but I don't
have any rule filtering on content. The SPAM module adds a header, so you
use a normal header matching rule to deal with these.

I am not sure what exactly do you mean. KMS has a build-in version of
SpamAssassin and is able to mark e-mail as SPAM. You can configure it how
to affect the mail. You can discard the message, forward it to a different
address, return the message to the sender or mark it as SPAM (optionally
modify the subject above certain score) and then let the recipient of the
message decide what to do with it. The typical setup is to mark the message
and the recipient has a server based Sieve rule that says "move messages
marked as SPAM in folder xxx" and maybe discard SMAP above certain level.
