Question : Exchange 2003 SP2 will not send or receive SBS2003 SP@

The Exchanger server stopped working middle of the day with no rhyme or reason, nothing in the error log to why stopped.  After backing up and finally reinstalling along with IIS still will not receive.  An email was sent in house and received but that stopped working with in a half an hour.  Have checked MX record, and smtp diagnostics run through MX toolbox all connect to smtp.  Firewall has been ruled out and nic changed on the machine. No mail externally or internally.

Answer : Exchange 2003 SP2 will not send or receive SBS2003 SP@

Okay - looking healthier now in terms of receiving.  I can run a domain report and can interrogate your server : )  I would imagine sending is a little happier, but some issues to address.

Your server FQDN is exchange.yourdomain.local.  This needs to be changed to mail.yourdomain.org and ths is done on the SMTP Virtual Server properties, Delivery Tab, Advanced Button.

Then call SBC Global and ask them to setup Reverse DNS on your fixed IP address with mail.yourdomain.org and then you should be much healthier.
