hi,

( Dovecot + Postfix + MySQL + Postfixadmin + Spamassassin + Clamav + Amavisd-new ) I need help and sample how to.

spamassasin, clamav and amavis don't concern dovecot: they should be integrated in your postfix setup - there are tons of howtos for that on http://www.postfix.org/docs.html

for dovecot you should take a look at http://wiki.dovecot.org/moin.cgi/VirtualUsers - I don't know postfixadmin, but I bet they have documenation on where the relevant bits for authentication and mailstorage (which is basically all that dovecot will need) are stored in mysql.

you only need to put the pieces together ;)

MfG,

Nikl
