I looked but was unable to find a simple addon that will check a specific imap or pop address and post any messages sent to the mailbox to a specific forum.
Here's how it would work. After installing, I set up an email address that includes pop or imap access. I then put the connection details for the account into the addon. A cron job then runs every couple of minutes and checks the mailbox for any new messages. If it finds any, it creates new a new post for each message in a specific subforum, pasting the headers and message body into the post.
PHP's built in libraries could be used to fetch the email:
Either pop or imap would do.
The use case here would be help divide the work of responding to emails sent to an email address. It could be used for contact us emails or for anything else where there is a steady stream of emails (our forum has several projects like this).
The idea would be to use the forum to create a very primitive support ticket management system. Emails sent to a public support email address would get dumped into a private subforum that is visible only to the team of people who are in charge or responding to the emails. Members of the team could divide up the work of responding to the emails using a forum software that they already use regularly. They could document their progress in the resulting thread, giving a simple way for people to monitor who is following up adequately on their responsibilities. Different members of the team could discuss how to respond to the various tickets/emails there as well.
While a standalone product would work well, this might also be easily integrated into SimpleForms (an excellent product) as well. @LP-John .
