Nigel - I can't send emails and as I don't know your private email address you'll have to put up with this.     You helped me join Eurona on Monday from Iberbanda.  Before you came I sent and received emails as per normal.  In the evening I was able to receive emails but when sending I got an error message that the IP address I was issued with was blacklisted as an originator of spam.

I contacted you and your advice was that I must have a virus or a trojan but I could appeal against the blacklisting and get it lifted.

I did.  It was.

On Thursday night the blacklist was back on.

I appealed.  It was lifted.

I have used every Extermination site I can find to get rid of any unwanted malware and each one shows no infection.

My ISP in UK confirms Eurona issued me the IP address which is causing the problem.

I am totsally unhappy with your assertion that I must have a virus as I understand I would be aware if I was sending multi address spams.  Additionally if, as you assert, I have an infection then it must be sometime during leaving Iberbanded (a slow and expensive but faultless system) and logging on to Eurona. 

I am the innocent party here and I'm looking to you and Eurona to sort out this issue without delay.

RSVP asap.

Nigel - Tks for yours.  I cnfm I am able to send over Iberbanda but when I try to send over Eurona I get the following error message:

QUOTE:An error occurred sending mail: The mail server sent an incorrect greeting:  Your IP address is on the XBL blacklist! Sending denied.

I further advise I'm unable to send over Eurona from my #2 laptop which has not been used for over 3 weeks ....  so if the #1 was infected at the time of changing companies, the # 2 cannot be.

The fault is undeniably down to Eurona and/or the IP address it has issued me.  A prompt solution will be gratefully received.

At 03/06-0950: both machines not able to send over Eurona. IP unblocked. Now on Iberbanda, IP= 83.230.189.92.
I'll wait to hear from you before re-connecting to Eurona tomorrow as per your (1).  Phone if you wish. C.

24 hrs on and the ip is still clean. So, connect #2 and see what happens - DON'T us it for mail yet - wait 12 hrs (use it to browse) and check the IP on spamhaus.

Spamhaus still says your IP address is clean - it hasn't been blocked since you disconnected your machine.

So, is it Eurona or your machine??

If it hasn't been blocked while you haven't been connected but does block when you connect what is the deduction? A Eurona problem or a machine problem?

I'm assuming your IP address hasn't changed either on Eurona or Iberbanda but the Iberbanda one IS listed in Spamhaus as violating email sending requirements :
This IP range has been identified by Spamhaus as not meeting our policy for IPs permitted to deliver unauthenticated 'direct-to-mx' email to PBL users
http://www.spamhaus.org/query/ip/83.230.189.92

Connect #2 to the Eurona connection and browse for a few hours then see if the IP is blocked. If not, try it with mail and see if it keeps working.

Process of elimination I'm afraid - and the evidence is pointing to an infected machine. The infection isn't one that is easy to find as it hides itself extremely well and many scanners etc. do not detect it.

Hi ColinB
My experience with blacklisted IP addresses suggests that it can be a frustrating exercise. Some of the blacklists are slow to respond to delisting requests, and therefore it can take some time for an IP to get fully delisted (several weeks in one instance where one of my webservers was concerned).
I don't know how Eurona allocate IP addresses on Wimax connections. If they are dynamically allocated from a pool (likely) rather than being static, then it may be that if you shut down your connection for a period of time (overnight, for example) - i.e. power off your modem box, then when you turn it back on you may be allocated a different IP address from the pool. If so, and your systems are clean, then you'll be home free.
Just a thought.
Good luck with it.

Spamhaus has not blocked your IP for several days (I have been checking regularly 188.119.192.56 so I assume you aren't connected or your IP address has changed and the block is following your machine. What is your current IP address and to which network are you connected?

Your 'old' IP address 118.119.192.56 is still clean - has been since you disconnected from it and stopped sending mail.

Your 'new' IP address has been blocked by Spamhaus. http://cbl.abuseat.org/lookup.cgi?ip=188.119.192.40

So, the problem has followed your machine.
