Re: Problems emailing Yahoo (only)

I looked up the public address of the server that Optus are using for this mailbox and it's listed on the PBL at Spamhaus.

 

Spamhaus says this is pretty "usual" and that it should be sufficient to set up SMTP authentication on the client machine that's sending the emails (I think)...Yeldarb do you think this would be the case?

Re: Problems emailing Yahoo (only)

No I don't believe it would make any difference and my own Optus account is authenticating with the smtp server.  The down side to ISP email is that many people are sharing the same mail server and all it takes is one spammer or one infected computer to have that IP blocked.

Re: Problems emailing Yahoo (only)

I have the same issue aswell. 

Keeps saying 

delivery temporarily suspended: lost connection with

   mta7.am0.yahoodns.net[74.6.137.65] while sending RCPT TO

Reporting-MTA: dns; mail104.syd.optusnet.com.au

X-Postfix-Queue-ID: CAA0C43BB16

 

How do we get around this?

Re: Problems emailing Yahoo (only)

Yep that one is on the blacklist as well. I guess if you can't get another mail server IP by either restarting your modem or waiting till it changes itself then emailing Yahoo might be out of the question. Optus webmail may also be another option. Keep in mind that these blacklists are common and many organisations other than Yahoo use them.

Re: Undelivered email - seeking postmaster address

Thank you, chloesok.

The problem is with the Yahoo server which has blocked my (and others') Optusnet emails.  I spoke to an Optus employee yesterday who said they had no information on this problem and told me to lodge a complaint, which I have done. Friends with Yahoo email acounts have been enquiring of Yahoo. It seems that Yahoo requires the Optus administrator to contact Yahoo.  I shall try the live chat today.

Re: Problems emailing Yahoo (only)

you can request a RBL de-iist with spamhaus without issue (Optus, not end customers!!!)

 

SORBS however forget it...we had one of our mail servers when I worked at ECN listed on SORBS for 4 years and they refused to remove it.  This is why I dislike RBLs, they are nothing but vigilantes and a law unto themselves (ISPs have sued in the US and lost vs RBLs btw).  

 

The only work around is to use smtprouting and use a SMTP server that isn't black listed .
