I am trying to send a mail via sendmail command in ubuntu terminal like this:
sendmail EMAILADDRESS
FROM: FROMADDRESS
SUBJECT: hello world
this is a test email
.
I don't get any error in console, but in the logs I get the next line:
localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA-v4
What could I do? I don't know how to do...
Thank for helping!
