I started to take a look at
blocking dialup and dsl IPs. I don't use an RBL for this, and I have my reasons.
So I want to handle the BL myself in my access list. (Yeah I hear you
grumbling!)
I was looking at spam IPs,
checking them in ARIN, and writing down the blocks to block. I started to think
about the consequences of blocking a range of IPs. Then I realised my own email
server would be blocked by this method! *eek*
I'm using a DSL line on my
email server. Which is part of my ISP's static DSL pool. I don't send thru my
ISP's mail server. I'm starting to see the error in this now. In my mind I had
somehow split the difference of HOME DSL and BUSINESS DSL. I always agreed that
HOME DSL users should always send thru their ISP's mail server, but figured
BUSINESS DSL didn't have to.
I've never been
blocked.....yet. But an admin with good intentions like my own could. So I'm
somewhat in a quandry. Does anyone block IP ranges manually? Should I focus on
using my ISP's email gateway?
Sorry this isn't SA
related. But is spam related.
