I am unable to send email to yahoo or the emails to yahoo are being delayed?
This is a new feature of yahoo mail. It is using what is called Grey Listing to fight spam. For more details, you can read:
What happens is that whenever a new message is sent to yahoo, it
replies with "try again later" message. e.g. here is a test smtp
connection to one of the yahoo's mx:
# telnet 126.96.36.199 25
Connected to 188.8.131.52.
Escape character is '^]'.
421 Message from (a.b.c.d) temporarily deferred - 4.16.50. Please
refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html
Connection closed by foreign host.
Now as you can see, yahoo did not even give us (the ip of a.b.c.d) a
chance to start the smtp session. What it will do is wait for us to try
again later. Our mail servers (or yours on your vps/dedicated server)
will try again later and if yahoo likes the delay long enough, it will
let the server communicate further and deliver the email.
To avoid such delays and problems with yahoo mail, you are
encouraged NOT TO FORWARD emails to yahoo or any other ISP. Please refer
to this KB as well why we are saying that:
Instead, use proper email accounts and use any of your favourite methods to read emails, i.e. webmail, pop3, imap.
has been having many problems lately while they are upgrading the
classic mail. Many can't access their mail at all. For now you can use
this link to send and receive, it's basic, but it works. http://us.m.yahoo.com/p/mail
Works for me.GOOD LUCK...........
