I've found a couple of mail clients that add an extra space after FROM:, this patch allows this optional space.

That space is already supported - the mailFromRE already has the \s? in it and the test coverage for spaces begins on smtpd_test.go#L141.

The change you've made in smptd.go actually removes support for the space in the To: field.
