Manual cleanup of email bounces

Related: item3756-Manage-email-bounces

This will soon be easier: https://gitlab.com/tikiwiki/tiki/-/merge_requests/1879

Steps

1. Look at most recent bounce
2. Determine email address it was sent to.
3. Determine type of bounce and course of action
   • soft bounce
     • vacation message, just delete message or archive?
   • hard bounce
     • email account no longer exists: delete from our system
   • other bounces
     • Your mail server is flagged as a spammer. You can contest here: http:// (We should do this once our system stops sending spam)
4. Search through whole data set for all uses of that email, and implement decision
   • You need to log into each Tiki association site
     • https://tiki.org/tiki-adminusers.php Generally running latest stable Tiki version uses new mail server
       • https://tiki.org/tiki-admin_notifications.php
     • https://dev.tiki.org/tiki-adminusers.php Generally running latest stable Tiki version patch applied manually uses new mail server
       • https://dev.tiki.org/tiki-admin_notifications.php
     • https://doc.tiki.org/tiki-adminusers.php Generally running latest stable Tiki version patch applied manually uses new mail server
       • https://doc.tiki.org/tiki-admin_notifications.php
     • https://themes.tiki.org/tiki-adminusers.php Generally running latest stable Tiki version patch applied manually uses new mail server
       • https://themes.tiki.org/tiki-admin_notifications.php
     • https://profiles.tiki.org/tiki-adminusers.php Running Tiki 21 LTS patch applied manually uses new mail server
       • https://profiles.tiki.org/tiki-admin_notifications.php
     • https://branding.tiki.org/tiki-adminusers.php Running Tiki 21 LTS patch applied manually uses new mail server
       • https://branding.tiki.org/tiki-admin_notifications.php
     • etc.
     • Since InterTiki is in place, you can manually edit user information. So deactivate InterTiki, clean the data, and reactivate InterTiki. We have a task to ease this.

Things to watch out for

• 1 hard bounce is not necessarily enough to delete email.
• A single bounce message can be for many emails (if you multiple emails to the same domain). So you can't delete it until you have addressed all of it.

Essential

• It's great to have a tool to categorize between soft and hard bounce, and count. But we also need to be able to read each email. Thus Cypht access somehow.

Potential feature request

• Add an exclusion list for emails never to be written to
  • temporary (ex.: 30 days)
  • permanent
