Configuring mailx to Use a Google SMTP Server
- Google documentation: SMTP relay service setting https://support.google.com/a/answer/2956491?hl=en
First, you will need to make sure mailx has access to a valid Google certificate in an NSS certificate database. Firefox usually has it in its profile directory, but it is a good idea to initialize a private certificate database for mailx. This page explains how to do that Create a New NSS Certificate Database and Import Google's Certificate:
Assuming you provision root GMail SMTP access, move the certs directory created at the previous step under ~root as follows:
mv .../certs ~root/.certs
Configure /etc/mail.rc as follows:
...
account gmail {
set smtp-use-starttls
set smtp-auth=login
set smtp=smtps://smtp.gmail.com:587
set from="root@now510"
set smtp-auth-user=your.smtp.user@gmail.com
set smtp-auth-password=your.pass
set ssl-verify=ignore
set nss-config-dir=/root/.certs
}
TODO: try a per-user mail.rc that is read restricted because it contains sensitive credentials.
Test:
echo "mailx e-mail" | mailx -v -A gmail -s "test" somebody@example.com
