hi this is sasidhar,
we have CentOS5 with default sendmail configuration.
Initially it is sending mails to gmail, yahoo etc. last few days it is
not sending mails to yahoo.
In maillog I observed that for yahoo mails the stat value is deferred.
I tried everything by browsing google but I didn't find any solution
to this problem.
Finally I came here with lots of hope.
In mail queue there are more than 1 lack, most of them yahoo, rediff
etc. For gmail it is not giving any problem every mail is going.
please give any suggestions to solve this problem.
