I've just installed exchange (well did it yesterday) and I've got a domain pointed to mxrecords which points to my ip and incoming mail is fine... But whenever I send a mail from a user, it appears as sent from the users side (goes to sent items with no bounceback) but when i look in the queues.. theres an 'internet mail smtp connector labex01 - ntlworld.com smtp connector' (i'm sending to my ntlworld acc)
There are mails in there from yesterday and today and I have no idea how to make them go? Their status is set to 'Queued' but if i right click and 'force connection' and 'unfreeze' nothing seems to change it.

Any ideas?

Cheers

edit: it says the remote server does not respond to a connection attempt.. windows firewall is off, I've bridged networks from the VM to my machine and it has connectivity fine.. I've telnetted smtp.ntlworld.com 25 and it responds fine 220 ESMTP server ready and i am VERY CONFUSED ((

ok thats really really weird...
i did 'unfreeze' and 'force connection' a few times and then enabled logging on pretty much everything in exchangetransport and then all of a sudden i receive 3 emails
still, any ideas as to what would have caused it to not send \ common faults?

cheers mates

 

Are you permitted to relay emails threw NTL?

What happens if you send straight threw DNS? (As long as your MX & A records that point towards your domain/server have been updated you should be fine).

 

I'm not using NTL as a relay. It is configured to send straight through DNS. I've specified domain.com in exchange and tried to send to an ntlworld account. I'm sure ntlworld wouldnt be blocking my server from transport of messages.?

 

Sorry mate, to make sure we are on the same wave length, do you have a A record and MX record for your domain pointing towards your Exchange Server?

If you drop down into CMD and type nslookup then set type=mx then type in your domain name what happens?

 

In my domain registrar control panel under the dns settings page, i have an A record which points to my IP, and i've put that A record in my mx records. I have natted relevant email ports to my exchange server and like i said, can receive and send emails, but it seems to be very tempermental

My 2k3 AD domain is called dazlab.local
my domain is somethingdifferent.com

cheers for help mate

 

your not on a home user NTL connection by chance?

As far as I was aware (and I didnt think they had changed this), port 25 is filtered so that you cannot setup your own email servers on their network, mainly to prevent spammers etc..

To be able to do it, you would need a business package.

 

Yes I am, however I don't recall seeing that in my broadband contract, as people should be able to do what they want with their connection (illegal stuff aside). I'm sure they wouldnt do that, not to mention I have already sent and received email from my exchange server running on my broadband, it's just not consistent.

 

when you telnet (port 25) to your mail server from outside your network does that work fine?

 

Yep, see below

 

Try and create a new SMTP Connector and disable the old one.

 

Can you send mail from there?

mailfrom: "youremail"
rcpt to: "your ntl address"
data: jdjdj
.


Something along those lines been a while since i did it.
