I just purchased a PIX 501 and thought I could get it configured without problemssince my set-up is simple. I also have experience with Linksys and Sonicwalls but since I'm in the big leagues now with Cisco, I'mbeing humbled.
I have a simple set up. 1 Static IP from my ISP that is PPPOE and on the inside I use a 192.168.1.x address. My workstation works fine and can access all I need outside but I'm not able to get smtp, pop3 & www trafic to my server from the outside. My serverIP is 192.168.1.11
The configuration file is below. Since I'm not very schooled on the CL, I have been using the PDM to create my configuration. If you could reference PDM in your reply, itwould really be helpful.

The acces-list on the outside interface contain in the Destination the public IP and not the private IP !
The Static has also the wrong syntax
Change the setup to:
name 192.168.1.11 mydomain.com
access-list outside_access_in permit tcp any interface outside eq www
access-list outside_access_in permit tcp any interface outside eq smtp
access-list outside_access_in permit tcp any interface outside eq pop3
static (inside,outside) tcp interface www 192.168.1.11 www netmask 255.255.255.255 0 0
static (inside,outside) tcp interface smtp 192.168.1.11 smtp netmask 255.255.255.255 0 0
static (inside,outside) tcp interface pop3 192.168.1.11 pop3 netmask 255.255.255.255 0 0
access-group outside_access_in in interface outside
After that to a < clear xlate >

I didn't get it to work as you described. I added the following and now I'm able to get email and web traffic.
access-list outside_access_in permit tcp any any
static (inside,outside) tcp interface smtp 192.168.1.11 smtp netmask 255.255.255.255 0 0
static (inside,outside) tcp interface www 192.168.1.11 www netmask 255.255.255.255 0 0
static (inside,outside) tcp interface pop3 192.168.1.11 pop3 netmask 255.255.255.255 0 0
The above opens up everything from what I can tell and obviously that isn't good.
I'm at least making headway and learning along the way.
Thanks for the help - without it I wouldn't have anything working.

Try again with:
# Figure out your Public IP (outside interface):
show ip
show interface
# Then add this lines but replace 'YourPubIP' by your Public IP:
access-list outside_access_in permit tcp any host YourPubIP eq www
access-list outside_access_in permit tcp any host YourPubIP eq smtp
access-list outside_access_in permit tcp any host YourPubIP eq pop3
no access-list outside_access_in permit tcp any any
clear xlate
