[Gllug] new types of spam

[mimo]

Interesting to hear this. The deylays have an explanation, and I think 
you could say it's also a problem on the client side. Let's say you send 
an email to someone and their server is down (and secondary as well). 
What should your mail server do? I think SMTP RFC specifies that your 
MTA should try to resend the message for a couple of times for certain 
period of time. It's reasonable to assume there could be a network 
problem or mainteneance downtime or something like that. In which case 
it would be good to, let's say, wait a couple of minutes and send try 
resending the message again.
This is all that greylisting expects. Apparently, quite a lot of mail 
servers (NTL!!! -- who said they are embarassed their system is this bad 
and are working on it), especially 'home' installations are not 
configured or cannot even be configured to take care of this very 
plausible scenario....
