Hello;

We have problems sending email to yahoo accounts from one server ....

Here is the exim log...

2006-10-29 15:29:21 1GeIDZ-0007fM-8W == [email protected] R=lookuphost T=remote_smtp defer (-53): retry time not reached for any host
2006-10-29 15:29:21 1GeIDZ-0007fP-EL == [email protected] R=lookuphost T=remote_smtp defer (-53): retry time not reached for any host


I have replaced original name with xxx and yyyy for the email accounts in the above log.

We can ping yahoo domains ...

I even went on to stop/flush firewall and check emails .. still the same error.

SMTP tweak is also disabled on the server.

Other details:-
[email protected] [/var/cpanel/users]# netstat -anp | grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 31502/exim


Resolv.conf looks ok and reverse dns is already up for the server.


The same email is recieved at hotmail or gmail accounts.


Please advise.



Thanks
