Hi!
I need some help how to allow smtp traffic to a exchangeserver on lanside.
I tried:
access-list out-to-in permit tcp any host 192.168.0.3 eq smtp
access-group out-to-in in interface outside
static (inside,outside) 192.168.0.3 xxx.xxx.xxx.244 netmask 255.255.255.255 0 0
Do i need to work with more outside ipadresses? Maybe it could be a bad overlap?

Is xxx.xxx.xxx.244 the address that is routable on the Internet ? If so change your config to the following
remove this static statement
static (inside,outside) 192.168.0.3 xxx.xxx.xxx.244 netmask 255.255.255.255 0 0
Add this one
static (inside,outside) xxx.xxx.xxx.244 192.168.0.3 netmask 255.255.255.255
change access-list from
access-list out-to-in permit tcp any host 192.168.0.3 eq smtp
access-list out-to-in permit tcp any host xxx.xxx.xxx.244 eq smtp

when i add your static my internet is no longer availble. Neither is it working to access smtp from outside interface. Can i use the same adress for outside interface as i use for my static routes or do i need to create i Global outside ip-pool?
Confused!

Change the static statement from
static (inside,ourtside) xxx.xxx.xxx.244 192.168.0.3 netmask 255.255.255.255
to
static (inside,outside) tcp interface 25 192.168.0.3 25 netmask 255.255.255.255
I'm assuming your mail server internal address is 192.168.0.3

Thanks for your reply! I added some more static statement and access-list and now i'm getting performance issues from inside firewall (not sure from outside). When trying to send or recieve files it's really slow. We have 10/mbit up/down via fiber. Works good with other firewall (dlink).Is there a more effective way to open up for ports www, ssl ,rdp, smtp to internal exchange server 192.168.0.3? All these static just doesnt feel right...

Hi! Please look at my update!
Thanks!

reverse the ip addresses in your static statement.
should be: static (inside,outside) xxx.xxx.xxx.244 192.168.0.3 netmask 255.255.255.255
The first ip is the global address the second is the real address.
