Cisco Config not processing internal webmail script

sorry, did not include enough detail

ok, as per above, i have an single windows box that handles IIS / DNS / 3rd party email server

now, i am sure you guys will ask if my email server works, and yes, it does. note the following below

1) you can send an email to any hosted domain i have and i WILL receive it.
2) i can send an email to anyone on the internet via my hosted email accounts with no issues

issue,
i have a webmail script (url http://www.aais.com.au/cdosys.asp). this just sends a test email to admin@aais.com.au which resides on mail.aais.com.au (and yes, this email account works (as per above)). HOWEVER, this script cannot find the email server which is on the same box.

so to add more detail, if i use a machine (other than the server) to telnet into the SMTP server (mail.aais.com.au), i will get a response. if i telnet from the SERVER itself and do the same thing, telnet mailaais.com.au, i get cannot find server.

the questions below have been asked before (from other locations other than EE) and i have answered them.. see below

(3) When you type in http://www.aais.com.au on your internal network you hit your router http page instead of your server.
correct. unless i modify my host file. THIS has now been rectified as my cisco config script has been changed to suit this.

(2) Your DNS server points for xxx.aais.com.au at your external IP
correct .. all dns entries are external IP's

(1) You have your own DNS/WEB/Email server sitting on the internal network at 192.168.0.11
correct, all services residing on the same box .. hence all my forwards to the one box

i am for certain this is NOT a server issue. this is (from opinions) a cisco config routing issue. i have included said config below for your review and comment's where available.

any help / assistance on rectifying this would be great
cheers

wow, that was simple...

i will give this a shot tonight and advise how it goes

quick question though, if i do modify the host file with the entry above, would it not effect the packet to always goto 192.4168.0.11? when it should be sending out to the external IP address? just worried about those who send an email from say .. hotmail .. to an email address of which i maintain, will the server just keep looping trying to find mail server?

thanks Irmoore

didnt get a chance to update the host file.. will do it tonight .. but i dont think it help the external users (web site) as it would only look for local address .. and when say i do modify the host, the external users (web sites) would not have 192.168.0.11 as my local machine, and not theirs

also, i did telnet into 192.168.0.11 25 and i did get a response from within that machine

well, did the local host file thing, and it worked

odd, but ok .. cheers for that
