Now I run a rootserver and want to host the domains by myselve. I have to deal with the mails in this case and I want to have web access. And by the way I did browse the faq, unfortunately I did not find how to deal with the following scenario.

You might want to check out fetchmail.

If you plan on filtering all the incoming mail in the mail server (which 
is the only way when you have several incoming mail servers that filter 
the mail then forward it to an internal server, for example), you will 
need a mail scanner which in addition to spam filtering can also use a 
virus scanner to scan your mail (e.g. ClamAV). I use AMaViS and it works 
great with Postfix.

Also, FYI, one advantage with Cyrus is that your email users do not have 
to have shell accounts on the mail server. Cyrus uses SASL to 
authenticate against a whole bunch of different backends, including 
LDAP. Hope that's useful.
