Tested more with fresh git version 2.7.1.380.g0fea050 (from git's git)
 # equery list '*' | grep -i smtp
dev-perl/Net-SMTP-SSL-1.30.0
mail-mta/ssmtp-2.64-r3

It seems the delay is caused by git-send-email trying to resolve
workstation's FQDN.
When I add "smtpdomain = localhost.localdomain" to [sendmail] section
in gitconfig, it proceeds immediately.
The same behavior (including workaround case) happens with
openmailbox.org and fastmail.com for me.
BTW "smtpEncryption = tls" in gitconfig seems to mean STARTTLS, so
using fastmail's TLS port 465 doesn't work at all, you need to use
587.
