No, it is very easy. All I had was a static IP from my service provider |
| 11 |
and a router with port 25 forwarded to an internal mail server host. |
| 12 |
|
| 13 |
To get the mail working all I had to do was create a domain name |
| 14 |
(using the free service at freedns.afraid.org) and point it at |
| 15 |
my static IP. |
| 16 |

I think it is possible to setup a MX record explicitly, but I have |
| 18 |
never bothered because so far everything that has tried to sent |
| 19 |
mail to it has worked fine defaulting to using the A record in |
| 20 |
the absence of a MX record. |
