along with your SMTP access-list. From there, if the DMZ server is supposed to send mail to the inside server, then your SMTPINSIDE and static that you have shown should be enough. What do you get if, from the DMZ server, type:
> telnet 192.168.185.50 25
If you get connected then the static/ACL is working as it should. If this is a Exchange server you may need to turn of the SMTP fixup with:
> no fixup protocol smtp 25
Other than that, whenever you have connectivity problems, always enable syslogging with:
logging cons debug
and try a connection, the PIX will then tell you exactly what it's allowing and/or denying.
