mail temporarily deferred by yahoo

some users complain that they could not sent email to yahoo. so i tried to find out why. i begin from the log of qmail-send, this is what i found (with minor edit) :

1. grep the username of the yahoo.com

$ cat current | tai64nlocal |grep username@yahoo.com

result :

2007-12-29 08:57:51.942276500 starting delivery 41246: msg 1547115 to remote username@yahoo.com

2. grep the delivery number

$ cat current | tai64nlocal |grep 41246

result :

2007-12-29 08:57:51.942276500 starting delivery 41246: msg 1547115 to remote username@yahoo.com
2007-12-29 08:58:00.330462500 delivery 41246: deferral: Connected_to_66.196.97.250_but_greeting_failed./Remote_host_said:_421_
Message_from_(xx.xx.xx.xx)_temporarily_deferred_-_4.16.50._
Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/

3. go to http://help.yahoo.com/help/us/mail/defer/defer-06.html but directed to this URL instead

http://help.yahoo.com/l/us/yahoo/mail/original/abuse/index.html

no good information there so i click the link Yahoo! Help Central at the he bottom of the page which lead me to

http://help.yahoo.com/l/us/yahoo/helpcentral/

4. click Mail at Help for more Yahoo! services menu leads me to

http://help.yahoo.com/l/us/yahoo/mail/index.html

5. since i am a postmaster so i click the postmaster link which leads me to

http://help.yahoo.com/l/us/yahoo/mail/postmaster/

6. look at the SMTP Error Codes menu and click 421 Message from (x.x.x.x) temporarily deferred – 4.16.50

here is what it said :

if you’re seeing the error “421 Message from x.x.x.x temporarily deferred – 4.16.50”, in your SMTP logs (where x.x.x.x is your IP address), this indicates that emails from your mail server have been generating substantial complaints from Yahoo! Mail users.

This is a temporary error and your mail server may automatically re-try sending emails at a later time. However, if you’re seeing this error consistently over an extended period of time, we encourage you to provide us with detailed information so that we can help diagnose your problem.

For bulk mailers, please visit this page to review our best practice recommendations and request assistance.

If your mail server does not primarily send bulk mailings (e.g., you run a personal, corporate, educational, or ISP mail server), please fill out this form instead.

If you are not the administrator of the mail server in question, please contact the administrator directly with the error message you are receiving.


7. i click
provide us with detailed information link and fill the form, submit it and wait for the result……. πŸ™‚

8. the statement from number 6 above which said This is a temporary error and your mail server may automatically re-try sending emails at a later time. could be true because when i grep again i found this :

$ cat current | tai64nlocal |grep gregor_gede

result

2007-12-29 08:57:51.942276500 starting delivery 41246: msg 1547115 to remote username@yahoo.com
2007-12-29 09:04:32.019166500 starting delivery 41248: msg 1547115 to remote username@yahoo.com

9. so i grep again

cat current | tai64nlocal |grep 41248

result

2007-12-29 09:04:32.019166500 starting delivery 41248: msg 1547115 to remote username@yahoo.com

Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/

:(( still deferred….. i guess i just have to wait for the result of the form submission above….. to be continued……… πŸ™‚

10. i’ve been browsing again and found this article that convinced me that i’m not the only one

11. i’ve checked my inbox and found a reply from yahoo saying :


Thank you for contacting Yahoo! Customer Care to answer your question. A
support representative will get back to you within 48 hours regarding
your issue. Until then, feel free to visit our online help center at
http://help.yahoo.com/
for answers if you have not already done so.

12. i checked my inbox today (january 2, 2008) and found a reply from yahoo dated December 31, 2007 4:50 am. the reply message is not satisfying at all…. there are 3 links to follow up. i’d already visited 2 of them the other day. 1 link is to fill another form, it’s a Yahoo! Mail Whitelist Form the link is :

http://help.yahoo.com/l/us/yahoo/mail/yahoomail/postmaster/bulk.html

i’ll try to fill the form later.

13. i checked my inbox at yahoo to see wheter my mail from the deferred server arrived or not. it was there πŸ™‚ …. finnally. so my conclusion so far is :
mail will be accepted by yahoo after some period of time. here’s the log on the defered server for the accepted mail :

$ cat @4000000047749e380e26eeb4.s| tai64nlocal | grep 40716
2007-12-28 10:47:20.584753500 starting delivery 40716: msg 1547033 to remote username@yahoo.com
2007-12-28 10:47:25.190973500 delivery 40716: success: 66.196.97.250_accepted_message./Remote_host_said:_250_ok_dirdel/

i sent the mail at 08:57:51 and finally accepted by yahoo at 10:47:25. so my mail server had to keep trying to send the mail for about 2 hours before it finally accepted by yahoo server. i think it’s not good…. πŸ™
