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
