mail from exchange server not reaching external recepients

hello Experts,

running exchange server 2003 (SP2) and mail is being relayed from ISP to this exchange server.  when i send a mail from my hotmail account to my mail address on this server it gets through and if i reply it hits the hotmail account fine. the problem is that if i create a new mail message within outlook and send it to my hotmail account, the mail never arrives and there is no NDR.

in exchange system manager, i have allowed the IP address of the ISP's mail server access and relay. it seems to work when i send a mail from hotmail to the exchange box but not when i create a new mail message.

appreciate any help/advice

yea, that's pretty strange.


I see you said you added the IP address of your ISP and everything seems right?


Are you using the default SMTP Virtual Server or do you have a SMTP connector?  I would suggest creating an SMTP connector if you don't have one and select the option "Forward all mail through this connector to the following smart hosts", then add in your ISP's mail server.

Lastly, if you have a spam filter, verify that it's not checking your outgoing messages and stopping them from being sent out.  (Which is unlikely since your message is being delivered).


If all that fails, I would suggest contacting your ISP since they are the ones who is hosting your email and it could possibly be something wrong with their side which is why you're not receiving an NDR.

trace the message with the message tracking center and see where it goes.


if you don't have message tracking enabled, follow this:

Paste in here what it says about the message

well, from the looks of it, it is leaving your exchange server successfully and went to hotmail's server.

Make sure the message is not in your hotmail junk folder.

thats what i thought too. checked hotmaill junk folder and nothing there. funny thing is that the same output is recorded when i reply, using outlook (work) address to the mail recvd from hotmail address. this one actually gets delivered into hotmail inbox...........that is weird ????



anything else worth checking ?

hi,

traced the problem to our ISP. the MX record pointing to our exchange server was missing (ISP couldn't tell me why this happened). Once MX record restored, I can receive emails from outlook to hotmail.

thanks for your help
