Mail servers are being "blacklisted".

  Number six 19:46 07 Mar 04

In recent months, myself and several of my friends have had an occasional problem sending emails. Their messages are returned as undeliverable because the sender's mail servers are apparently "blacklisted" by the recipient's. The usual reason given being that the sender's service provider are running "open relay" servers. This has only started happening in the last couple of months. Anyone else had similar problems? Comments?

It shows one of the major drawbacks of anti-spam operations which rely on blacklists: innocent users get caught out. Frequently I find that mailwasher incorrectly marks mail which comes from AOL users as being "origin blacklisted".

Who are their ISPs?

I had an email "undelivered" stating that the recipient's isp was not accepting mail from my source, or something similar. The recipient was with AOL and my own ISP is BT Yahoo BroadBand! Anyone else? Is this due to "blacklisting"?

I have just run a quick test, using my 4 mail accounts with different providers, and once again one in particular will not accept email from the other three (BT, Freeserve, Tiscali). It will also not accept messages from my brother's account (blueyonder broadband). Over-zealous policing, me thinks. Jakey boy, you're lucky this has only happened to you once!
