Need some help - (exchange server 2003)

civic minded · Postby **civic minded** » July 22nd, 2011, 9:36 am

I know there is alot of IT people here so here goes,

I have a SBS 2003 setup to route emails via the Exchange Server 2003. I got fedup with TSTT in the area -(internet service very unreliable). That we sighed up for Flow Digital Broadband. I setup everything correctly using a static ip address they gave me for my network card mac address. I got connection to the internet. Everyone can access the internet and bandwith is no problem.

The only problem i have is that i cannot send mail. My smtp queue buildsup and no emails are going out. All settings are correct and Flow tells me that there isnt any NAT or firewall to block.
I have telnet port 25 and ping the mail servers - everything connecting but i am not getting anything.
I then went into the Routing and remote access where the firewall settings are located and enabled DHCP for clientlookup and DNS clientlookup - emails started to move but not all of it. I do not have ISA or cisco routers setup, just the basic firewall supplied by SBS 2003

Only when i switched back to TSTT all of the emails move and no problems till i switch back to flow..

What am i doing wrong??? someone please help.

Sounds like a MX issue

I have content filtering on - using RBL and others. The static IP is clean (thats what flow tells me). The errors that i am getting back said that non-communication with SMTP.
I do not have any coporate firewall enabled, only when i get this issue sorted out i will turn back on the cisco firewall.

yup, mx record, btw, this takes approx 18 hours to populate so dont expect it to be instant depending on who host your mx records.

^^some emails are passing thro the exchange as normal but some are not.. some gmail accounts are getting thro and some other gmail accounts are not.

what is your retry interval on the server?
try to raise the time to retry and see if it helps
view your message queue and see if it does the 3 retries and times out

This sounds to me like the MX records or a problem with routing. If i m not mistaken you said that when you switched back to TSTT everything worked. It might be a setting with the SMTP service also.
I am assuming you are currently on flow. Try the following
Shut down the smtp service on the server you are running exchange and also any service associated with SMTP and exchnage. It will tell you what service will be shut down.
restart the service.
If this dose not sort out the problem it is definitely some sort of routing you might need to add your flow IP address to your DNS record on the dc.

i can provide more info. but based on the information provide those are the possible fix above
there are many possibe problem that might cause what you currently experienceing

OP, did you use this tool for your domain and try the mxlookup and SMTP tests?

civic minded · Postby **civic minded** » September 9th, 2011, 5:22 pm

^^MX record is setup correctly - TSTT no longer have the MX record, Only Flow have it. And yes i used the MX toolbox and everything is what it suppose to be. I have restarted the SMTP service and i think it worked.
Mail is moving and my users are not complaining anymore. I will still monitor it and let you all know.
Thanks for the number MadCrix - i will call if it continue
