If the smtp variable is set, a SMTP connection to the server specified by the value of this variable is used instead.  

i.e.

echo "message" | mailx -S smtp=localhost:10025 -s "subject line" -v [email protected]

重發 EML

-t

The message to be sent is expected to contain a message header with `To:', `Cc:', or `Bcc:' fields giving its recipients. 

Recipients specified on the command line are ignored.

# -v     # Verbose mode

cat 1.eml | mailx -t -S smtp=localhost:10025 -v
