NAME
extsmail — robust sending of e-mail to external commands
SYNOPSIS
extsmail [options ...]
DESCRIPTION
extsmail masquerades as the standard UNIX sendmail(1) when messages are sent; effectively,
it notes the command line switches passed to it, and puts those, and the message contents
read from stdin, into a file in a spool directory for later sending with extsmaild(1).
Use extsmail online using onworks.net services
