Email only moving one way

[sunkentek]

Hello,
So I have exchange 2003 and I have the STMP set to my correct URL, the MX record has been edited. OWA is configured to require SSL and I am using NAT to forward requests from the internet to the exchange server (ports 25/443) I can receive email from my gmail account to the SMTP account that I set, however when I reply I get nothing on the other side. Any suggestions as to what I should look at?

Your exchange queues. And make sure SMTP logging is on.

So you can send email from your exchange server to gmail? But not from gmail to your exchange server?

Thanks for the reply, I can send email from gmail to the exchange server, but not from the exchange server to gmail.

I looked inside the exchange queues and I see gmail.com as a folder. It has the last 5 emails I tried to send from the exchange server and its status is retry. I tried unfreeze and force connection. I did go in the system manager and drilled down to Servername, properties, Diagnostic Logging Tab. there I MSexchangetransport and set SMTP to max. Where do I find the logs files? in the event viewer?

 

[sunkentek]

I found the log files in system32/logfiles
Should I post the log file?

HI,

How is your exchange configured to send mail out?

Are you set to send mail out through your ISP's SMTP server or using DNS?

Cheers

In the IIS SMTP, are you smarthosting and are you using specific DNS or the Windows DNS?

 

[mofusjtf]

Another thing to try is sending to another domain besides GMAIL. To see if it is specific to gmail or other domains.

And as the other posters have suggested. Check your SMTP configuration. If you're set to use a smarthost make sure that is correct. If you're set to use DNS, make sure your DNS settings are correct.

Any update on this?

 

[sunkentek]

Ok, sorry for the delay.

I have configured my outgoing SMTP by going into
Server manager/first organization/admin group/first admin group/routing group/first routing group/connectors/

I created a connector and set it to use DNS, in the bridgehead I added the Exchange server from the list.
Under address space I added the name of my url
<urlname.com> cost set to 1, type SMTP.

 

[Zelandakh]

Try address space * and ensure you are using Entire organisation for the scope (same tab).

Can you surf from that server?

 

[sunkentek]

Yes I can surf the internet from that server. I will change that setting from a url to the wildcard *.

Thanks again for all the advice.

 

[Zelandakh]

No worries, but do post back.

 

[sunkentek]

Ok, so I changed the address space to "*" and selected "entire Organization"
I can recieve outside mail but still am unable to send out.

Try to telnet to a mailhost on port 25 from your exchange machine. If you get a timeout when you try to connect your ISP is probably blocking port 25 and only always mails to be routed through their smarthost or relay server.

To lookup a mailhost use cmd:

nslookup
>set type=mx
><domainname>

and you will get the mx records of the remote domain.

 

[sunkentek]

Thanks, after attempting to telnet and it timing out I checked with my ISP and they do infact block outgoing port 25.
Could I setup exchange SMTP to use a different port?

 

[Zelandakh]

You can but you'd need to get every other email system in the world to follow suit to allow you to communicate with them.

Suggest you call your ISP and get them to unblock - they shouldn't block your company email...

I have found that most consumer level internet packages block port 25. They make you upgrade to a business level package to have full access to port 25.

 

[sunkentek]

Thanks for the info guys, this isnt a company Exchange server, but rather my lab at home for learning and testing. Is appears that earthlink blocks only the outgoing SMTP traffic on 25, so i dont suppose that I could some how route that traffic some other way could I? Also they do prove an SMTP server for me to use with my outgoing clients on an earthlink SMTP, is there a way I could configure Exchange to use that for the outgoing messages?

[Zelandakh]

Yes, in your SMTP connector there is the option to relay out - put smtpauth.earthlink.net in there.

 

[sunkentek]

Thanks, I noticed that earthlink and several others require that you authinticate to the server in order to use SMTP. I lloked around and the only place i found that appears to allow me to set up a username and password for this is in outgoing security in exchange. Is this the correct place for me to add my earthlink username and password to authitcate over the earthlink SMTP?
