I have tried all the usual mailing list apps (phplist, dada, mailman) but none do exactly what I want. The requirements seem fairly straight-forward but I can't find an app or service that meets all of them:
- Paste or input a list of users (create users not send out invitations)
- Create and manage groups of these users as mailing lists (some users may be on multiple lists)
- Associate lists with an email address so any user can send an email to the whole list (must be sent to the list automatically or with a cron job) - I don't want to have to use a web interface to send emails.
- Needs to be able to handle HTML emails and attachments
Unless I am missing something none of the apps I have tried can do all of this. PHPList came the closest with the mail2list plugin but it does not work reliably and attachments fail.
