Comcast network so every once in a while my IP changes, normally I go into my ISP dns and update the record and my mail starts working again but for some reason not this time. My internal mail works fine. When I send from yahoo mail I get 4.4.7 returned mail errors. When sending From an exchange account I get Delivery Delayed errors. I went to websitepulse.com and did an email validity test and got a “connection timed out” message. No significant errors that I can find in the event logs all seems to be working fine but no in/out exterfnal mail……any Ideas on where to look next?? Any Ideas on where I should look next?
