DA won't send welcome email

[Dunk]

I've just changed my nameservers and now DA won't send out welcome emails to users.

[nobaloney]

Not enough information.

First step is to shell into your server and try:

$ nslookup nobaloney.net
If that works you can probably send me mail. If it doesn't, then you most likely cannot send me mail because the servers in your /etc/resolv.conf file aren't cacheing nameservers.
