Nigel - if the problem is following my machine then I simply do not understand why I can send emails without difficulty from a wi-fi node in l'Ampolla.  If the machine is infected wouldn't the emails be blocked?

No, your machine isn't blocked, the IP it is connected to however is. If you left your machine connected to the WiFi node long enough then the IP address would presumably be detected by Spamhaus as an infected IP address (or, better described an IP address with an affected machine connected to it) and blocked.  This takes time so it would need to be connected for a while before it was detected.

Did you read through the description of the reason it is being blocked?

One possible thing you can try additionally is to force any attempts to send anything to 78.47.46.141 to a dummy IP address. This will only work for that address though and it may change.

This can be done by editing the file:
C:\Windows\System32\drivers\etc\HOSTS and adding the line:

127.0.0.1 78.47.46.141

to the end. The file will look a bit like this:

# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#      127.0.0.1       localhost
#      ::1             localhost
127.0.0.1      localhost

127.0.0.1 78.47.46.141 this entry will route all your data to a server in Germany .. See screenshot.  I do not understand what he is trying to achieve there as if it is a dummy address then your internet may cease to work

    It was last detected at 2013-06-08 02:00 GMT (+/- 30 minutes), approximately 6 days, 12 hours, 29 minutes ago.

CBL report.  If you have no problem using hotspots then it is your ISP at fault
Why do they insist on giving a static IP and why will they not change it


Nigel      -     I'm getting very fed up.

well, last Monday, three weeks after joining up everything cleared and I was able to send emails without any problems.  Most or all consulted authorities agree I did not have any form of infection but my problems were caused by the IP addresses I was given.  It seems that an IP code given to someone in the past can come back to haunt you.....everyone I hsve consulted agree I have not had, now or in the past, an infection.  I am and will remain a little curious as to why one particuar Reputation website, CBL, should single me out whereas a score or more did not find me to be a problem.   The final outcome, Nigel, is that I am really disappointed with your support.  I had to fight my corner all the way with no support from you or Eurona.  I look forward to a competitive supplier.

As there have been over 1100 visits to this thread I feel I ought to bring things up to date.  After the three weeks or so of having my outgoing emails blocked, suddenly everything returned to normality as reported above and I happily sent emails as normal.   
We have builders in, and some weeks later they switched off everything for over 24 hours.  On resumption of Internet connectivity we found we had been issued a fresh IP address (as one would expect) but when we tried to send an email found we were unable to, as we had been (Oh! You guessed….) blocked.  Again I checked all the internal IP addresses and scanned everything to the deepest available depths without any viruses being detected,  and then opened up an old laptop that hadn’t been used since February this year.  And what a surprise?  Outgoing emails were blocked – proving beyond any doubt my equipment was NOT at fault.  And yes, I did check that routers and modems do not have the same sort of IP address as the emails and so cannot be responsible.  I spoke with Nigel Morton and the Eurona help desk and sometime later normal services were resumed without any feedback, apology or reasons given.
All is well?  Not quite.  Over the last four weeks we have found that on numerous  occasions the Eurona telephone line was dead, even though the Internet worked perfectly.  The only way we know the phone was dead was when someone called on the mobile and said the obvious, or we noticed we had only two lights on the Eurona modem instead of three.  Each time I texted Nigel Morton, and sometime later the line was restored (without feedback so I don’t know if he did in fact do anything).
However, the last time, Saturday, I received the following text from him, “I can’t do any more than advise (you to) reset the equipment as there is a change in the support procedure.  For more support u need to phone Eurona 910444888” (My emphasis) So – if you thought you have local help from your local agent think again.  You will have to phone the help desk and hang on, and hang on - at mobile charges of course as your landline will be dead - Nigel Morton did not elaborate on what the changes are.   
Am I being neurotic in thinking I’m getting a bad deal from these people and why am I  losing an important connectivity?   Unhappily Eurona offers a faster speed at a lower price than Iberbanda….but one has to wonder which gives the better service over all.  And now – dare I turn off the modem for 24 hours and get a new IP address?

Telefonica / Iberbanda are terrible companies to deal with.
Even the staff in our bank here, have had problems with them. Our solicitor has a pile of letters and demands, which these companies keep sending out to his clients.
He even told us to ignore any communication from them now!

I think the majority of people find Nigel very helpful.
The Eurona, usually works very well, for most of us.
It does go down sometimes, in bad weather, or if they are doing maintenance work. On the whole it's good.
Could it be something to do with your electricity supply, fluctuating, that causes some problems, maybe?

I would like to say we have always found Nigel very helpful BUT he does eat all my biscuits upon his visits.
Yours a biscuitless Bulldog. xxx.
