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 that is based upon Berkeley Mail 8.1, 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.
Setup for send mails with external smtp server

Remember that this configuration is system-wide.
