The Situation:  I'm testing my web app on a server in my basement, connected to the internet through Comcast.  The app should send email at various times to mailboxes I've setup with my GoDaddy domain.

The Problem:  Some emails come through ... most don't!

The Reason for the Problem:  The email being blocked contains a hyperlink to the server it's being sent from.  The URL in this hyperlink resolves to the IP address given to me by Comcast, which is actually flagged in the Spamhaus Block List!

... Why am I being flagged? ... Why me?!

Well, Spamhaus gives you a reason for being blocked and here is mine.  According to the Spamhaus Policy Block List (PBL), all IP addresses starting with 24.xxx.xxx.xxx are flagged!  Turns out there are over 16 MILLION IP addresses who will suffer the same fate.  Who's to blame?  Spammers.  Is this a good solution?  Hell no.  Hopefully SPF will put an end to this madness.

Solution:  I guess I'll remove links to my own server.

Better Solution:  Get an ISP with unrestricted access to the internet!  I've heard good things about SpeakEasy.Net, but I haven't tried them out yet.
