Hi

We have recently changed from leased line to Broadband and also have changed provider. Sometimes our outgoing mails get stopped and the following message appears "There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.", we had a SMTP connector in place for the old lease line so i created a new one for the new provider. Firstly is this correct and if so can i have 2 connector (have old one stil there as backup)

thanks
Mark

Hi

Yes we are using DNS, I didnt change the DNs forwarders.  I am checking with the ISP to see what they are, should i flush my dns on the server?

I would also make sure that you do not have a smart host configured on the SMTP virtual server.

no go into your dns server-go to the dns page and update your forwarders to point to the external dns servers that your isp use
than do the dns flush

You do nothing to your reverse lookup zone locally, but if you have changed ISPs then you need to ensure that the ISP has set the reverse lookup on the new IP address.
