Connections not accepted from IP addresses on Spamhaus
In our continuing efforts to protect our users from unsolicited email, Yahoo! Mail does not accept SMTP connections from:
If you are seeing this error message, please do not retry sending your message using the same IP address.

If you think that your IP address has been listed in error, you or your email administrator should contact Spamhaus. Once your IP is delisted by Spamhaus, Yahoo! Mail will automatically unblock your IP within 48 hours.

Stop all this jibber jabber, what does it mean?

Either your IP address, or your SMTP server IP address is blacklisted on spamhaus.org. Yahoo is no longer accepting email either from your computer, or from your SMTP server. This is a permanent error that needs action from either you or your SMTP server administrator (depending on who is on the blacklist).

Did I do something wrong?

Perhaps; if it is your personal IP address that is blacklisted, then yes, although if you are certain you did not send spam, your computer may be infected with a virus or Trojan Horse. It may also be that the problem resides at the SMTP server you are using in your email software; in that case, it is the SMTP server IP address that is blacklisted and not your personal IP address.

How can I fix this?
