Mail not accepted from blacklisted IP address

  Pineman100 16:54 02 Aug 2008

I run XP Home and my ISP is Tiscali. I have a friend in France who runs Vista and his ISP is Orange.

Over the last few days he has tried to email me several times. Each time, the email is bounced back to him, with the report: "550 Mail not accepted from blacklisted IP address (". The bit in brackets is an IP address.

We have checked very carefully, and there's nothing wrong with the email address that he's using for me. I can email him without problems, and he can email me from his Gmail account successfully.

He is even less computer savvy than me, so I'm trying to help him sort out this problem. What I need advice on is where it is likely to be occurring. Do you think it could be:

1. Something in his firewall?

2. A problem with

3. Tiscali blacklisting

4. Something else?

Item 3. seems inconceivable, because Orange is such a major ISP, but I suppose it has to be considered as a possibility.

Has anyone got any ideas, please?

I would look at the settings on the firewall first.

Thanks to all of you. From Jak_1 and Sea Urchin's responses it certainly looks as though problems sending emails from Orange to Tiscali aren't new. But my friend has been sending them to me for years with no problem - I wonder why this has suddenly cropped up.

I think I'll contact Tiscali's technical support people and see what's going on. I may be a lot older by the time I next post on this thread...!

I have received a reply from Tiscali Support, which confirms that the Orange IP address has been blacklisted. No explanation for this is offered. In order to lift the blacklisting, here's what Tiscali say:

"To resolve this issue, the owners of the blacklisted Domain/ISP can request to get this removed by contacting Spamhaus at: [email protected]. The Spamhaus Block List (SBL) is a real-time database of IP addresses of spam-sources, including known spammers, spam gangs, spam operations and spam support services."

I've passed this to my friend in France, and I'm hoping he can have some success.

Many thanks to everyone for your contributions to this thread.

The problem here is with Orange mail server IP address, its being listed in some SBL blacklists. It really is up to Orange tech support to get this resolved and get those mail server IP's off the spam database.

As a rule, I would never use email services supplied by ISP's, my BTYahoo email is a good example of this (some email servers see all email from BTYahoo as slighly spammy).
