SBS 2008 exchange 2007 help

[deca300]

Hi everyone,

I have a sbs 2008 server running exchange 2007. My router packed up. I changed the router. Internet works fine now, but can only send and receive local email. NO external mail can be received or sent??
What could this be?
The mail is hosted on the local exchange.

You need to forward port 25 to your Exchange box

What router is that?

Depending on the kind of router, you'll need to check for a "portforwarding" or "virtual server" section.

You'll have to add a rule, something like

incoming = 25
destination IP = 192.168.1.1 (change this to your exchange2007 server's IP)


It depends on the router, not all have the same interface/layout.

ASSUMING you're using a static IP and already got MX records pointing to your static IP...

Otherwise you'll also need to set up your dynamic DNS hostname...

Libs is bang on the money

You can go to portforward.com to find the instructions for most routers to enable specific services,for mail I usually do the following

25 - SMTP ( Receiving mail from outside )
143 - IMAP ( Users with tablets and smartphones can connect to IMAP )
110 - POP3 ( same as above but Pop3 rather than IMAP,so not synched between all devices )
587 - Alternate SMTP submission ( mobile users on ISPs with redirected port25 access,give to employees to use your smtp rather than ISP one )

like above, are you using fixed IP? or dyndns?

i have spent many nights being through in the deep end with this sbs thinngy ma bob, but gotten fairly good at it, almost got the courage to migrate to sbs 2011

thanks for the replies. It is a Dlink router. What do I need to do on the router for this to work again?
