On a ubuntu system I have installed postfix and set relayhost and mynetworks in /etc/postfix/main.cf config file.
I can now telnet to port 25 on this server and send an email by issuing the SMTP commands. I ran a test to a gmail account and received the email message ok.
But on the same linux host I installed mail (apt-get mailutils) and ran this command:
mail -s "test email" myname@gmailcom
entered some message text and Ctrl-D and saw no errors but message is never received by recipient.
Do I have to configure the smtp server in mail config somehow? Should I see the messages in some sort of queue waiting to be sent?
Any tips on how to resolve?
Some more info:
my /etc/mailname config file contains the string: mail.mydomain.com and my linux box is not configured with a domain (it is only a test system). Should I change this to just mail? (mail is hostname of box).
I found a mail syntax which allows you to specify the sender which works for me:
mail -s "message 5" -a "From: [email protected]" [email protected]
But I would prefer to fix so I don't need to do that.
Here is the error I see by using mail interactively:
