Subject: Allow e-mails to be sent with the Unix sendmail tool
X-Git-Tag: v0.15-rc1~171
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/a0fe60a231b08ce3cba4b8cdcbc4db68ae160116

Allow e-mails to be sent with the Unix sendmail tool

If the stgit.smtpserver configuration option has an absolute file path
format, it is assumed to be an external tool. For example, to use
sendmail just set this variable to "/usr/sbin/sendmail -t -i" (see the
examples/gitconfig file).
