Hmmm that's not a bad plan, but I could some cases whee that might |
| 10 |
cause some issues. However overall it's probably better solution than |
| 11 |
just blocking port 25 access to anything, but your own servers. |

However back in '99 talking your dialup proviiders into tossing CPU |
| 14 |
eating ACL's onto their gear was hard enough let alone doing something |
| 15 |
complicated like hijacking smtp. I think even today it's hard to |
| 16 |
implement something like that unless you own most of the gear involved |
| 17 |
which isn't always the case. |
