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.
