Error sending email to yahoo account

Submitted by andrewrimmer on Mon, 10/25/2010 - 13:04

Hi

I get this error in the header of returned email from yahoo.

The ip is for personal use and only personal email, so there is no chance it has been abused by me. Could telnet be causing a unsecure proxy problem, which I read may be a reason for it being rejected.

xxxxxx@yahoo.co.uk: host mx2.mail.eu.yahoo.com[77.238.184.241] refused to talk to me: 421 4.7.1 [TS03] All messages from 188.241.116.247 will be permanently deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html

It sounds like Yahoo thinks they received a lot of email that looks like spam from your IP address.

One explanation for that is if a spammer broke into a web app you have, and is exploiting that to send spam. You may want to see if there's a lot of mail in your mail queue, which you can verify by typing "mailq" on the command line. I'd expect to see a few messages there, but if you have hundreds, that's unusual.

However, another explanation is that it's a problem with the previous owner of your IP address. Running a test against other RBL's, none of them are blocking your IP address, it just seems to be Yahoo.

If you only recently acquired that IP address, the problem you're seeing could have been caused by the previous owner.

Thanks

Only 3 messages in the queue all for yahoo, the ones I sent.

I only got the ip a few months ago, so I will email yahoo from their website.

Thanks for your help.

Yeah, they should be able to lend a hand in figuring out if the issues are recent or not. Let us know if you have any other questions!

I had such issues with Yahoo too in the past, concerning my static home IP address, which I had been operating (without spam incidences) for many years. Yahoo has a slightly odd behavior there concerning what they consider "peculiar email traffic".

Filling out that web form of theirs should get you removed from their blacklist.
