Subject: send-email: Change from Mail::Sendmail to Net::SMTP
X-Git-Tag: v1.3.0-rc1~6^2~2
X-Git-Url: https://git.octo.it/?p=git.git;a=commitdiff_plain;h=4bc87a28be020a6bf7387161c65ea3d8e4a0228b

send-email: Change from Mail::Sendmail to Net::SMTP

Net::SMTP is in the base Perl distribution, so users are more
likely to have it.  Net::SMTP also allows reusing the SMTP
connection, so sending multiple emails is faster.

[jc: tweaked X-Mailer further while we are at it.]
