# extsmail(1)

robust sending of e-mail to external commands

## NAME

**extsmail** – robust sending of e-mail to external commands

## SYNOPSIS

**extsmail** \[*options* *...*\]

## DESCRIPTION

**extsmail** masquerades as the standard UNIX [sendmail(1)](/sendmail/1.md) 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)](/extsmaild/1.md).

## SEE ALSO

[extsmail.conf(5)](/extsmail.conf/5.md), [extsmail.externals(5)](/extsmail.externals/5.md), [extsmaild(1)](/extsmaild/1.md)

## AUTHORS

**extsmail** was written by Laurence Tratt ⟨http://tratt.net/laurie/⟩
