====Hi all,

First of all, I'm very new to linux and try to setup my own mail server, kindly be easy on me:) I finished the setup on fresh OS. When I tried to send mail, it is not sent.

I tried command:
sendmail -bp

return:
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
37154C71777F      522 Fri Aug 26 13:36:32  test@xxx.com
                   (connect to 127.0.0.1[127.0.0.1]:10026: Connection refused)
                                         test@xxx.com

=====================

I tried command
service amavisd status

return

===================

I have tried to completely disable amavisd, the mail sent successfully. However, that's not a good solution.

I have no idea what else to try, kindly need your help.

Thank you.
