Runnig Bind 9 on Open Bsd 3.3

Mail server was working prefect. I had 3 ip address running on one machine. I had to use one for another device. that was the ip I was using as the"mail server".

SO I switched it to one of the others but now I'm getting connection refused when i try to connect using webmaster@africanstudios.tv.


I can check my mail under webmaster@66.166.100.220.

I check my services and everything running
I used dig, nsloopkup but can't find any thing wrong please advise.

According to DNS - your MX record is to mail.africanstudios.tv which is IP 66.166.100.221. That may be where your problem is.

Another possible problem is that the reverse lookup doesn't come back to that name (mail.africanstudios.tv)

You might want to insure your ISP has updated your records (if they are running your DNS).

Your 66.166.100.220 is ready to receive email -

$ telnet 66.166.100.220 25
Trying 66.166.100.220...

Escape character is '^]'.

But what is strange (unless you are changing things right now) is that 66.166.100.221 is also ready to receive email - even though it's not listed as a MX in DNS (make sure you disable any Sendmail that you won't be using - folks have been known to use them as relays or will use it to spam your company):

$ telnet 66.166.100.221 25
Trying 66.166.100.221...
Connected to 66.166.100.221.

(Added note - I tried again to telnet but to the normal POP port but could not connect on either IP - it may be that you haven't included it in your /etc/services )
