HELP! ISP is Spam Blacklisted...
I already opened a support ticket on this, however wanted to discuss the topic...
My ISP here in Asia is blacklisted as a spammer. When I send out mail, my own machine's IP address (Given by the isp) is listed in the email, and is caught by spam checking software. Even though my SMTP server is Fastmail's... By association, my emails are listed as spam. How can I keep from being blacklisted by association with a bad ISP?

Rob, So glad you replied. Here is what SpamCop is saying in the headers...
RCVD_IN_BL_SPAMCOP_NET 2.5, RCVD_IN_SORBS_WEB 1.456, RCVD_IN_XBL 3.897, TVD_FW_GRAPHIC_ID3 2 I cannot get rid of the BL, I guess, unless you are able to help me somehow, how about the others? I havn't been able to get a good answer on this through fastmial support... Apparently the XBL has to do with Relay... I have a domain at Fastmail... How do I get rid of this "relay" error? I use mail.messagingengine.com as my smtp server, is this correct? Thanks! |

As I said:
"Since it sounds like the other side is parsing the Received headers, the only way to avoid it is to use the web interface, which doesn't add your IP in Received headers..." Unfortuantely there's nothing you can currently do when sending via SMTP, because your original server IP is always included in the Received: header, and since the other side is parsing through the received headers, the'll always find your IP. If you send via the web interface, then no IP is added, only the FM server IP is used, which should avoid the BL hits. Rob |

This problem results from what to my mind is a very unfortunate position taken by some (all?) of these blacklists. When they blacklist a dynamic IP address, or a block of addresses, or essentially a whole ISP, they are hoping that that the innocent users they are hurting will take action against the ISP to force it to better police its addresses from the spammers. I don't know whether this actually ever succeeds (anyone have some success stories?), but it can definitely hurt those who can't really defend themselves. Isn't this sort of like imposing severe economic sanctions against a country hoping that the unarmed population will rise up and overthrow the undesirables running it? |

One possiblity is to lessen the weighting of the ISP's ip address, and increase the weighting of the SMTP's IP Address. Out of the hundreds of people I email, only Fastmail is processing my email this way, and it is ironic that it is my own email provider. RCVD_IN_XBL 3.897 This refers to the email being Relayed by a spam provider. Why does it think I am relaying my email? Thanks! |

I don't believe these scores and hits have nothing to do with the FastMail side.
Maybe there's a bit misunderstanding here. From what you're saying, my understanding is. 1. You have an internet connection at an Asian ISP 2. You send email from your machine via FastMails SMTP servers 3. You send email to someone you know at another email provider 4. Your email is being blocked at the other email provider due to your IP being on some RBLs Is this what you're saying, or did I mix things up? If so, I don't see how we can do anything about it. We can't change any scores, because it's the other provider that's running SA and causing your email to be blocked, not us? Rob |

The "Other Email Provider" in this case is Fastmail.
The only reports I get of my emails being labled spam are people from fastmail. I would assume that other providers using SpamCop also will have this problem. But, at the moment, the problem seems to be contained to fastmail users. CL Last edited by ChinaLamb : 5 Mar 2007 at 09:23 AM. |

Ah I see now!
Thinking about this, there is unfortunately no easy solution when sending via SMTP. The IP your connecting from was clearly involved in spamming activity in the past, so any email you send from it is tainted by the RBLs it's listed on. The only solution at the moment I'm afraid is to use the web interface which doesn't include the sending IP in the Received headers. Rob |
