GMail and Yahoo Mail servers not accepting mails from my slicehost slice

  • 772

I have a rails in one of the slices at Slicehost. I've setup postfix (sendmail) to send emails from my rails app.

All emails to Google Apps domain (to company setup google hosted paid email id) are getting delivered properly (but to spam folder).

But all emails to [email protected], [email protected], .. @hotmail.com are not getting delivered and this is the line from my /var/log/mail.log

Dec 21 17:33:56 staging postfix/smtp[32295]: 5EB4810545B: to=<[email protected]>, relay=j.mx.mail.yahoo.com[66.94.237.64]:25, delay=1.6, delays=0.02/0.01/1.5/0, dsn=4.0.0, status=deferred (host j.mx.mail.yahoo.com[66.94.237.64] refused to talk to me: 553 Mail from 173.203.201.186 not allowed - 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; see http://postmaster.yahoo.com/errors/550-bl21.html [550])

and this is what i got for gmail

    Your ip address (of the slice) is blacklisted at SpamHaus.

    That is why emails are not being accepted. I would ask slicehost to provide you with a new ip address.

    HEre is a link to check blacklists: http://www.mxtoolbox.com/SuperTool.aspx?action=blacklist%3a173.203.201.186

    Here is an article on how to get the ip removed from spamhaus but keep in mind the chances of being able to remove it are dificult. it is easier to get a new ip from your provider. http://articles.slicehost.com/2010/1/20/removing-a-mail-server-from-the-spamhaus-pbl

    hope this helps.
