Manage email bounces

• Feature request
• Dogfood on a *.tiki.org site

Tiki sends emails for several things (watches, password reset, newsletters, etc.) in addition to end users via Cypht webmail.

System emails should be sent with a valid sender email. Many will put a bogus no-reply at example.org but that is bad practice. We should be using a real email account, accessible via Cypht.

There will be manual replies. There will be bounces. This should be monitored, and handled accordingly. When you have hundreds or thousands of bounces in a Cypht-accessible account, it's tricky and time-consuming to manage.

If you don't handle this, and repeatedly send out emails to invalid accounts, you risk being flagged as a spammer.

Tiki should help detect types of bounces. Ex.:

• Manual reply
• Soft bounce (ex.: vacation message)
• Hard bounce: (user doesn't exist)

There should be a dashboard of all bounces, with a way to see

• The emails with the most bounces (top bouncing emails so site admin can go in order of priority)
• The actual emails with Cypht

And help Tiki admin handle this

• Show where this email is used (user profile, watches, etc.) and help remove.
