okay, so I had to try this to learn and

andrew@basement:~$ dig +short bigpond.com mx
10 extmail.bigpond.com.

andrew@basement:~$ ping www.bigpond.com
PING www.bigpond.com (144.135.18.32) 56(84) bytes of data.
64 bytes from 144.135.18.32: icmp_seq=1 ttl=233 time=212 ms

cool, but...

andrew@basement:~$ ping extmail.bigpond.com
PING extmail.bigpond.com (144.140.80.13) 56(84) bytes of data.
64 bytes from extmail.bigpond.com (144.140.80.13): icmp_seq=1 ttl=234
time=364 ms

that's a different IP. looks to me like the MX record is wrong.

Am I doing that right?

Hi Andrew,

Bigpond.com isn't my site, it's the ISP that I have registered my domain
name with (ie encomium.com.au) and it seems to resolve fine via http, ssh
and ping.

Any email to <user>@encomium.com.au however gets the 'No server' message.

All I'm really trying to figure out is whether my mail server settings are
wrong or whether my ISP is redirecting my email traffic to force me to
purchase extra mailboxes on their servers. Is it possible for a DNS
provider to redirect traffic to a domain on a particular port (ie 25 and
110)?

Also if they are redirecting my mail to an account on their servers, say
blah@xxxxxxxxxxx, would it be possible to set this account up as the
primary mail repository? That is, if all email traffic for my site was
directed into this account, would it be possible to set my server up to
download the messages via POP, sort them by username, then forward them to
the respective recipients?

It was a common practice in my area that ISP's would block ports like 25 so
you couldn't run servers on a home account, or to prevent spam from
originating on their IP block. I don't think that is the case now but that is
something you may want to check. Telneting into your mail server on port 25
may give you clues as to what is happening when an outside server tries to
connect to your host.
