Hello

It's again about two weeks we wait for the UPC Austria Mailserver Techs to 
solve a problem. Unfortunately UPC Austria seams to have fallen deaf again, 
so I hope some techs from CC or UPC Austria read this list and could try to 
find out what goes wrong with solving that problem.

I had a tech from Austria telling me they had found the reason why they are 
mailbombing our customers.

After the Mail 'DATA Termination' according to: rfc2821
Section: 4.5.3.2 Timeouts

A sending Server should wait 10 Minutes for the OK.

UPC Austria has reduced that timeout to something under 90seconds.

Our Servers do check for Spam and Viruses during that Data Termination phase 
so the can reject such emails on the fly.

90 seconds just is not long enough for big emails from CC customers hitting 
our servers when they are a bit busy.

So UPC keeps resending those big emails filling up our disks and the mail 
quotas of several of our customers.

I doubt we are the only ISP which since is being mailbombed...

So if somebody from UPC Austria or Cablecom who could do something is reading 
this list, please tell the responsible mail techs that the problem still 
persists and that I'm still waiting for feedback.

We tell all our affected customers to tell the sender (which are Cablecom 
customers) to contact their customer hotline, but we get feedback that the 
cablecom customer hotline does not manage to get that problem solved either.

Kind regards

Benoit Panizzon
