S-nail is a mail processing system with a command syntax reminiscent of ed, with lines replaced by messages. It is based on Heirloom mailx, which in turn is based upon Berkeley Mail 8.1. It is intended to provide the functionality of the POSIX mailx command and offers (mostly optional) extensions for IDNA, MIME, S/MIME, SMTP, POP3 and IMAP. It is usable as a mail batch language.

Sending mail with an external SMTP server

Configuration files are $HOME/.mailrc and the systemwide /etc/mail.rc. Add the following text to the appropriate file, changing bold strings:

set smtp=smtp(s)://server:port
set smtp-use-starttls
set smtp-auth-user=mailuser
set smtp-auth-password=password
set from="Your Name <youremail@domain>" # optional

Testing and sending emails

To test the configuration:

$ echo "message" | mailx -v -s "subject" receiver@mail.com
