RE: Some thoughts about spam and SPF

Anyone using mail servers on these addresses: 81.221.18.144/29 could fake
email from pamho.net.

If you own then, then you are save.

But if the IP addresses are blacklisted then you may have trouble getting
people to accept email anyway.

As long as they do not use "exists" to specify specific users.

Using "exists" to specify users will tell a spammer which addresses to
spam and forge (because not every recipient will be SPF protected for
years).

The SPF record of pamho.net uses "exists":
v=spf1 exp=exp.pamho.net ip4:81.221.18.144/29 exists:%{l}.ses.pamho.org -all

Now tell me what addresses the spammer can forge.
