Description

An common setup is, that postfix will run as an smart host on the same server.
So it is ok to configure the mail settings like this:

MAILER_TYPE = smtp
HOST = [::1]:25

But this will not work, because gitea will always try to setup an secure smtp connection.
But for local host (::1, 127.0.0.1, localhost) it make no sense and will only results in error, because not certificates of official ca can provides an SAN entry for this address.

Workaround

Add this setting:
SKIP_VERIFY = true

But this is an dirty, it will munch better when gitea don't try to use smtps for local host.
And using sendmail is no option in many cases, because not all postfix milters will work there.
