I installed postfix with dovecot and mysql but I faced some problem...

First of all it seems like when I am starting the postfix process it's taking 20%wa ...

Than when i'm trying to send message from gmail to my mail box it seem to reach fast to the /var/spool/postfix/incoming/... but it's not coming to the defined mail dir in /home/vmail/domain/mailbox... Until I restart the postfix than it shows up there and it happens again and again, sometimes it reachs without restart but it takes quite long time. It's not problem with the server connection or speed because it arrives the spoll directory very fast so it might have somthing with the postfix process that stuck?

Another thing, when I try to send message to someone like gmail.com or other host it says relay host denied , how do I open all relay host? not just few I set manually.

Thanks very match!
