dovecot - Mar 2010 - Could use some help setting Dovecot up for the first time

Hi Everyone,

I've managed to get most of postfix and dovecot running using the howto 
located on dovecot.org.

So, I went to go test sending a email locally and i am getting this 
error which i cannot seem to resolve. Any help would be welcomed.

I usually find this type of message "Operation not permitted" to be a
permissions issue. Check that the user "deliver" running as has the  
needed permissions to work in your directories "/var/vmail".

Your userdb says mails should be accessed with gid=12, but you're calling
deliver from Postfix with gid=6. Change either one of them to the other (userdb
or pipe in master.cf).
