blacklisted Email problem

Asked by Xander

I get the following message when sending mail from my lubuntu laptop, strangely I can send/receive using my android tablet (using the same to and from email) without problems

Failed to transport message. Message sending failed since the following recipients were rejected by the server: <email address hidden> (The server responded: "81.158.46.118 is blacklisted in either CBL or Sorbs.")

I've been to CBL & Sorbs sites and reasonably sure the IP address above isn't listed as blocked.

anyone know what's going on?

I can receive mail, but after receiving finished the same "blacklisted" message, shown above still appears:(

Anyone know why? Is it something to do with my setup? I'm using Kmail...

The STMP server the mail is send from is blacklisted. It looks like it has an IP for a end-customer internet access IP.
What have you configured as the outgoing mail server (SMTP) in your mail client?

it's a freehostia email server mbox.freehostia.com:25, logging in with username and password (and it's allowing incoming mail).

BTW the IP reported in the message is my router IP

The IP is blacklisted, you will need to identify what is sending excessive emails then request removal.

Too many removals will get you PERMANENTLY blacklisted.

81.158.46.118 is not listed in the SBL

81.158.46.118 is listed in the PBL, in the following records:

    PBL231588

81.158.46.118 is not listed in the XBL

And from the FAQ:

Help! My IP address is on the PBL! What should I do?
 Nothing, in most cases. Read through this FAQ for further explanations.

The first thing to know is: THE PBL IS NOT A BLACKLIST. You are not listed for spamming or for anything you have done. The PBL is simply a list of all of the world's dynamic IP space, i.e: IP ranges normally assigned to ISP broadband customers (DSL, DHCP, PPP, cable, dialup). It is perfectly normal for dynamic IP addresses to be listed on the PBL. In fact all dynamic IP addresses in the world should be on the PBL. Even static IPs which do not send mail should be listed in the PBL.

PBL listings do not prevent you sending email unless your email program is not authenticating properly when it connects to your ISP or to your company's mail server. This can happen if you have forgotten to turn on 'SMTP Authentication' or if you have switched 'SMTP Authentication' off by mistake.

If you are using a normal email program such as Outlook, Entourage, Thunderbird or Apple Mail and you are being blocked by a Spamhaus PBL listing when you try to send email, the reason is simply that YOU NEED TO TURN ON 'SMTP AUTHENTICATION' in your email program's account settings. That will solve the problem for you. See: How do I turn on SMTP Authentication?

Server admins who need help with SMTP AUTH can find lots of information for most servers such as Sendmail, Postfix, Exim, Qmail, Exchange, etc.

However, it did point me in the right direction - clicked the "Server requires authentication" checkbox in Kmail settings and seems to be OK now, thanks for the info.
