Hello, Prabh.
Your answer lies in the info you provided:
domainkeys=neutral (no sig); from=digital-infotech.net; dkim=permerror (future timestamp)
Yahoo appears to think that your timestamp is off by some amount of time in the future.

Hello Mike,
that actually worked!! i configured ntpd & ntpdate & restarted the server. But when i restarted the server, dovecot failed to start on boot (it is virtual machine). with this error.
dovecot: dovecot: Fatal: Time just moved backwards by 537 seconds. This might cause a lot of problems, so I'll just kill myself now.
immediately then, i tried to send one email from command line, here are the results. WORKED !!
mta1001.mail.gq1.yahoo.com from=example.net; domainkeys=neutral (no sig); from=digital-infotech.net; dkim=pass (ok)
i am sure i can deal with dovecot problem.
Thanks / Regards Prabh S. Mavi
