Spoce.com is a customer domain.

MX10 adsl.spoce.com = end user ADSL connection with fixed IP address
195.2.133.196
MX20 adsl2.spoce.com = end user ADSL connection with fixed IP address
(redundency) 195.26.41.206
MX30 mail.saq.co.uk = SAQ (my ISP) backup smtp server 195.2.128.155
MX40 smtp.saqnet.co.uk = SAQ (my) ISP primary smtp server / secondary BIND
DNS server 195.2.156.65

In this case the mail SHOULD go to adsl.spoce.com = 195.2.133.196 presently
it does not, possibly down to a bad IP address range or an external routing
issue since mail will route to that address on the internal network.

Instead mail can not reach the primary or secondary MX so it goes to MX30
mail.saq.co.uk which queues the mail and then sends it on to the primary
address 195.2.133.196 - because the mail will route via the internal network
between the mail server, the ADSL gateway and the end user mail server.

Smtp.saqnet.co.uk will queue mail if any of the others are unavailable.

Hope this makes sense...
