I can not access anything outside the internal network from the FTP server. How do I confiure my ASA 5500 to allow the server outside access. I can not ping or access internet.

Hi,
You have a very restrictive ACL for your "dmz" interface
access-list dmz extended permit tcp host 10.2.2.2 host 10.1.1.11 eq smtp
access-list dmz extended permit tcp host 10.2.2.2 host 10.1.1.50 eq 8777
Can you add for example
access-list dmz permit icmp host 10.2.2.2 any echo
access-list dmz permit tcp host 10.2.2.2 any eq http
access-list dmz permit tcp host 10.2.2.2 any eq https
access-list dmz permit udp host 10.2.2.2 any eq domain
access-list dmz permit tcp host 10.2.2.2 any eq ftp
Or if you want to restrict that those services cannot be used to the LAN network then only add this configuration INSTEAD of the above one
access-list dmz remark Deny Rest of the Traffic to LAN
access-list dmz deny ip any 10.1.0.0 255.255.0.0
access-list dmz remark Allow Traffic to Internet from the DMZ server
access-list dmz permit icmp host 10.2.2.2 any echo
access-list dmz permit tcp host 10.2.2.2 any eq http
access-list dmz permit tcp host 10.2.2.2 any eq https
access-list dmz permit udp host 10.2.2.2 any eq domain
access-list dmz permit tcp host 10.2.2.2 any eq ftp
Or something else if you want. The above should allow all the basic services though
Since at the moment you have not allowed even ICMP or DNS

Hi,
Would be best if we saw your ASA configuration first.
EDIT: Seems you added them to the original post
