I installed postfix using >sudo yum install postfix postfix-mysql. I'm newbie to mail systems, but I have one AMAZON EC2 instance with a public DNS. I used the public DNS in most cases, when I configured the file main.cf. The public DNS I have is from amazon and it is a long string(ec2-123-34-234-677.....amazon.com).
// I configured this on main.cf. I replaced example.com with ec2-123-.......amazon.com myhostname = mail.example.com mydomain = example.com myorigin = $mydomain mydestination = example.com, $transport_maps local_recipient_maps = $alias_maps $virtual_mailbox_maps unix:passwd.byname home_mailbox = Maildir/
How do I test postfix? I just want it to send emails for my web
application. I tried to test it with
>telnet localhost 25 after I typed in SSH
>sudo postfix start. but I
recieve the message that telnet command can not be found.
I also use the Amazon linux distribution if you want to know. I use it
because it is free.
What have I done wrong? Are there anymore configurations required pls help!
