Connected to localhost.localdomain. Escape character is '^]'. 220 portal.aphroland.org ESMTP Postfix (Debian/GNU) helo portal.aphroland.org 250 portal.aphroland.org mail from: centos at linuxpowered.net 250 2.1.0 Ok rcpt to: centos at linuxpowered.net 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> Subject: hello there testing email (put a period here and hit enter) 250 2.0.0 Ok: queued as B5F52808041 quit 221 2.0.0 Bye Connection closed by foreign host. And see if the email arrives at the destination. It seems like the mail server is not working right as Oracle says it's returning a 421 error code(temporary failure). And if the telnet works, try it a second, and a third time to see if it's consistent or not. nate _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos ______________________________________________________________________________________________________ 付費才容量無上限？Yahoo!奇摩電子信箱2.0免費給你，信件永遠不必刪！ http://tw.mg0.mail.yahoo.com/dc/landing -------------- next part -------------- An HTML attachment was scrubbed...
