Our T1 is up

[victora]

We just moved from DSL to T1. Its been chaos since this morning. Its not like unplugging the DSL line and replace it with the T1. I guess we're just getlucky (with the help of our T1 provider), we are online. We're hosting our own web; that one too is up.

The PROBLEM now is our mail server. We are on Exchange 5.5. My question is: what setting we need to change on our mail server? I had the impression, we dont need to modify anything on the Exchange. If not, what else can we do to activate our mail server. Both inbound and outbound is not working.

THANKS A LOT...

I would imagine you need to check where mail is being forwarded on your Internet Mail Service / Connections tab as no doubt all your IP addresses have changed?

Well.. it all depends on where the actual mail is being delivered.

Was your ISP hosting mail - or was it being directly delivered to your exchange server? There could be a lot of steps depending on which option you have.

We have our mail server on site; its not hosted by our ISP. I'm suspecting its a matter of changing something on our Exchange. It was working fine during our DSL days. And also, yesterday, we were able to send outbound mails. Its just the inbound mails that are not coming in...

Thanks for your help

Yes .. well see... If emails were being deliver directly to your exchange server - then it is the MX records where your DOMAIN NAME is host that need to be changed. With your New T1 - you get a new set of IP addresses - and Name Servers. In order for your mail to be delivered - these MX records are needed so that mail from a sender can be properly routed to your new IP.

OR... another scenario as Andy has suggested, if your DSL Isp was acting as a relay for your mail - then you WILL need add MX records and setup DSN as i've mentioned above. or have the iSP for your T1 line act as a Relay (which I doubt they do.. but you never know)
