Description Thomas Fischer 2024-03-19 11:01:22 UTC 
Similar to the existing "Check Before Send Mail" plugin, Kmail should warn and ask for an extra confirmation if an email is about to be sent to a potentially large number of recipients.
Criteria to test for:
- Number of recipients in To, CC, and BCC fields is about a certain threshold
- A mail address previously configured by the user as a "distribution address" is used.

A "distribution address" would be a mail address like "everyone@example.com", where the mail server then takes are to distribute the mail to a large number of recipients.

Those check should not be limited to cases when the user chooses "reply all". Even a 'normal' reply to a distribution address should trigger a warning.

Implementation detail/suggestion: Before sending, KMail or Akonadi counts the number of mail addresses (To, CC, BBC). Every mail address which is in the list of known distribution addresses counts 1000 (or any sufficiently large number). The threshold for a warning is 10.
