[#1]

Hello, I configured exchange server behind fortigate ,The OWA is working properly and I can send email but cannot receive any email , I got this error " Sorry, no mailbox here by that name. (#5.1.1)" I just using Virtual IP , is there any special setting I missed ? thanks

Hi, please supply more information: - setup of your VIP - the policy the VIP is used in, including the services setting

information

VIP info Name :Exchange External Interface: WAN1 Type: Static NAT External IP Address/Range : Real IP that registered as MX record Mapped IP Address/Range :internel IP " actually IP of TMG server" Port Forwarding: none Policy Source :All Destination: Exchange Service: Any Action : Accept

Is the destination the inside exchange IP or the VIP definition? It needs to be the VIP to work.

[#5]

The destination is the VIP definition with the name Exchange , as you see above the name of VIP is Exchange & destination in the policy is Exchange

VIP and policy look OK. Do some more tests: - can you ping the server from outside? - can you telnet to the server from outside? enter HELO or ELHO and see if you get a response. If both tests run OK it' s not a firewall issue but a valid answer from the server. What do the server logs say?

I cannot ping either for the fortigate or the Virtual IP , I tried also to telnet & I got this Could not open connection to the host on port 23 connect failed

Then the public IP seems to be wrong. Please post - the public IP of your MX - the public IP of your fortigate, including subnet mask (if you want you may change one or two bytes, but not the rightmost) You can check correct routing from your ISP via traceroute/tracert. Where does it stop?

are you sure this is a Firewall issue? You get a response from your Thread management gateway (TMG) saying that there is no mailbox visible.

" Sorry, no mailbox here by that name. (#5.1.1)"

the firewall would completly block the connection saying nothing. Also outbound mail works. OWA works on the same VIP as well? The telnet test mentioned should go to port 25 talking SMTP. (#telnet ip port). Yours is defaulting to the default telnet port 23. (google for " telnet smtp test" ) i' d rather have a look into the TMG than the Fortigate. regards Maik

even when I tried to disable the OWA rule in TMG that publish the Exchange I got the error error , I think My SMTP ISP who is replied
