Hi, |

My first guess would be that your ISP, solnet, is blocking your port 25. |
4 |
|
5 |
Their MX can connect to yours because it is in 'their' network, but their |
6 |
firewall rules prohibit anything coming from their upstream provider to |
7 |
connect to their clients (maybe to prevent spam or what ever, maybe just |
8 |
for lameness). |
9 |
|
10 |
You could ask your provider for being unblocked (dumb idea when using a |
11 |
large ISP?). I don't know about your DynDNS provider, but if you really |
12 |
need a local MX you could switch to no-ip.com: they offer some service to |
13 |
get exactly around the problem you have, pretty cheap IIRC. I don't know |
14 |
how they implement this, i guess they set the DNS MX records to one of |
15 |
their servers and then forward them to some other port on your machine. |

i don't know about how mail servers react to ports being blocked. could be |
31 |
some/most/all really give up w/o notification. If Solnet *drops* packets |
32 |
to your port 25 this is probable. (someone correct me on this one if i'm |
33 |
wrong please?) |
