Here is an example of a newlsetter portlet I built a while back. This works in 4.x.x and will batch mail.

Basically this goes through groups, user groups, roles and makes a hash of all the email addresses, then shoots out an email to everybody.

Anyway to release this to the community to have work start on it? It is a great part of the user control experience.

Hi Brett,

in your code below you are using MailEngine to send emails. How do you know whether sending of an email failed or not?
