Hi
I have migrated to qmail from sendmail recently.
Since migration I have a strange problem, users started complaining they do not
receive some of the mails their counter parts send. I am using
qmail+vpopmail. I have tried some test mail from hotmail and yahoo. 90 percent
of mails from hotmail I have received properly, 10 percent received after a very
long delay. Where as fifty percent of mails from yahoo I have received and
remaining bounced with following message.
Message from yahoo.com.
>Unable to deliver message to the following address(es). > ><mrinal@espacetech.com>: >Sorry, I wasn't able to establish an SMTP connection. (#4.4.1) >I'm not going to try again; this message has been in the queue too long I have tried from a few other domains and many of
the mails bounces with the same message.
My mailserver continuously
available and my Internet connection do not seem to have any
problem.
Can Anyone suggest, what could be
wrong?
Regards
Mrinal |
