Alan Dekok has previously volunteered to write up a document going
through the entire SMTP model as it is today, and pointing out every
single section of it which is currently being exploited by spammers. The
next logical step would be checking which points in the model can be
adjusted and tightened to reduce spam.
Thank you. That's all I been saying.
Remember think!
connect ---> validate
helo/eho --> validate
mail from --> validate
rcpt to:---> validate
data---> validate
quit
Once you do this (properly) you will come to the logical technical
conclusions (I hope).
Ok, I think we'll all be waiting for his document very eagerly.
Hopefully he can provide a status update and perhaps let us know if he
needs more help.
