I know that was sometimes the case from the rejection message sent by |
20 |
the destination SMTP server. Even though I had a static IP address |
21 |
and an valid MX entry for the sending machine's hostname, some sites |
22 |
wouldn't accept mail because my static IP addres was in a block used |
23 |
for DSL customers (of which I was one). |

I've never run into that, but I know people who have. |

In either case, I wouldn't advise anybody to try using their own SMTP |
32 |
server to deliver mail directly to destinations unless they have their |
33 |
own domain, their own IP block, and the time+skills require to fight |
34 |
with the problems. Anybody with the requisite resources and skills |
35 |
probably wouldn't be asking questions here about how to use Gmail's |
36 |
SMTP server. |
