SBS 2008 Pop connector cannot connect to 'Local Host'
Hi,
I have a new install of SBS 2008 (2 weeks). Up until a few days ago, Exchange was working without any problem but now we are unable to recieve any external e-mails.
We are currently using Microsoft's pop connector (don't even get me started on whay they are not using SMTP) and it seems to connect to the external account without any problems but it is unable to connect to or send to the local host.
Keeping things simple, there are currently only 3 users and 3 pop accounts, each being delivered to their respective accounts - and again, it has been working without a problem since install.
Internal e-mails are ok.
Outgoing e-mails are ok.
External Pop account is ok (we are able to connect to and clear all mail, ensuring there are no errenous or oversized e-mails being downloaded).
No AV, Firewall or 3rd party security software etc (out of the Box SBS 2008).
All services have started (and restarted, and the server rebooted)
Error is immediate - no time out.
Authotative Domain is setup (was working originally)

I want you to telnet to localhost on port 25, from the SBS server.
helo with localhost also
from your log excerpts, localhost is what you are connecting to and you may have a firewall rule preventing access to 127.0.0.1 (localhost interface)

the fact that telnet to the servername works says the hub transport is running, lets just check on the localhost name resolution now...

Hi barrulus,
If I "telnet localhost 25", it says "connecting to localhost..." and then returns to the "Administrator: Command Prompt" with the standard "C:\Windows\system32>" displayed. No further telnet commands work after (as not connected).
I disabled the Windows firewall temporarily in case it was blocking it for some reason but this made no difference to the telnet command?
Thanks again.

can you ping localhost?
Also, try connecting to 127.0.0.1
telnet 127.0.0.1 25

Thanks,
I can ping 127.0.0.1, returning the server's IP address.
If I telnet, I get the Command Prompt as before (not telnet screen)
I have had a look at that post and am unable to fiond a solution - I have already created an Authoritative Accepted Domain in Exchange Management.

Ok, so that tells me not dns issues, tells me that there is simply no listener on the localhost interface.
In order to get this running you will need to create a new smtp listener.
This blog post from MS Exchnage team should help

Thanks again,
I have followed all instructions but am still unable to relay any mail to the exchange server / accounts.
The pop connector log reads the same!
I have restarted all services (even restarted the server).
Thanks for your assistance.

under "SMTP connector properties" > "Network"
"use these local IP's..."
You need to ADD 127.0.0.1 on port 25

If I try to add 127.0.0.1, an error comes up saying the values conflict with the Fax Sharepoint reciever and they must be unique.
Thanks
Thanks
ok then. so your sharepoint fax receive connector is using localhost port 25.
Is the fax service started?
Is the fax service started?
ASKER
There was no Fax service to start.
I went to the SBS Console > Network > Devices there was no Fax service installed so clicked on the "Start the Fax Service" to install the service.
The fax service now starts but seems to have made no difference. I also restarted the pop connector & transport services, in case it made a difference bot nothing.
