As designed acp>users>send mail>status=sent even when $config['enableMail'] = false;

You get a feedback within acp that the mail was sent fine when you disabled the setting in config.php and no mail was sent.

As a suggestion: to have a quick view of config.php in acp>"start page" - that would be great ! So you can see whether you have a cache enabled, whether you have disabled mail etc.

I see the point few admins use that option and then want to send out an email, though

Generally speaking, this is as designed. The option is there to "swallow" email and effectively send it to a blackhole. The returning false case is supposed to indicate an error.
