If you see this error: "The mail function has been temporarily disabled on this site, please try again later." then please check the Site Admin | Global Configuration | Server | Mail Settings and make sure that Send mail is set to yes.
If you are seeing this after an upgrade and Send mail is already set to Yes, then please try setting it to No, clicking Save, then re-setting it to Yes and saving again. It appears that there is a Joomla! bug in the 3.2 upgrade that adds a check to the mailer for this setting but does not create the setting in the site configuaration.
