My Home router (netgear dg834g) does not respond to requests for MX addresses from the internal network. Is this normal? It DOES respond to other reqeusts.
My previous router - BT Voyager 2091 - worked responded to both MX and non-MX requests.
I know it's unusual, but I run my own mailserver. After the router swap no outgoing email got sent. The email program (VPOP3) reported "427 No response from the DNS server - please check your settings. (failed)".
I ran Wireshark on the network and it was clear that the router did not respond to MX requests, yet it did respond to other DNS requests. Its not a negative response, it seems to completely ignore them.
As a workaround I have configured the VPOP3 program to use the Google public DNS servers that's working fine.
If I buy another router am I likely to find this behaviour again? Or have I just been unlucky?
Extensive Googling has not turned up anyone else with this issue. That may reflect how few home users run their own mailserver. I doubt it affects any other kind of usage.
