Comcast

Well, Frank was very kind to post his comment. But it doesn’t help.

…indicates the user name is invalid or there is trouble routing it to the Comcast.net server by the ISP or mail provider you use

he writes.

Well, there is a very well-known numismatic organisation in the USA and they use comcast. The CEO of the organisation has two comcast.net addresses. I needed to reply to an email which I had received from him – both emails bounced. This was from my bluewin.ch address. Then I tried using my gmail.com address – both emails bounced. I then tried my old web.de address – both emails bounced. I asked my brother in England to send the mails from his BT (British Telecom) address in England - both mails bounced. I asked an English numismatist living in Germany to send them from Germany – both mails bounced even though he tried sending them from two different addresses on two different mail servers, one of them being aol.com, the other t-online.de. The same applied when the emails were sent from the Professor of Numismatics and Archaeology at an Italian university. Both mails bounced. Finally I asked my friend in the US to send them – the emails got through.

So what Frank is again suggesting is that the DNS of all these mail servers, in Switzerland, England, Italy and Germany – are all set up wrong. The suspicious thing is that the email sent from Germany from an aol.com address was bounced, whereas the emails sent from the US from an aol.com address got through. So that puts paid to any DNS excuses and puts paid to any nonsensical “user name is invalid” rubbish.

• Fact is, emails from most European servers don’t get through.
• Fact is, comcast needs to stop blaming the error on European mail servers - where, by the way – email was invented (by CERN in Geneva, Switzerland).
• Fact is, no other mail server in the world acts in the same way that comcast.net does, by bouncing emails with such depressing regularity.
• Fact is, I am fed up with being humiliated by having to ask friends in the US to forward emails to comcast.net addresses.
• Fact is, US companies are certainly losing business and will continue to do so. (We finally gave up on ordering $12,000 worth of bicycle components from a firm in Arizona because emails to their comcast.net address kept bouncing).
• Fact is, that our (European) mail servers can find every other mail servers all over the world. But Frank says they can’t find the comcast.net server. So where is the error, hmmmm?
• Fact is, even a reply to Frank’s  @cable.comcast.net address bounced !!!
