Rephrasing to be sure I understand correctly.

When the checkbow is not ticked, claws-mail will always notify on cert
change. When it is ticked, it will silently accept certificates that
are valid according to one of the CA stores found in the system, but it
will still notify about new self-signed certs (in fact, any cert that
is not signed by a CA corresponding to the stores found on the system).

This is exactly what I need.

I guess I was in doubt because

- "valid" is ambiguous to me, perhaps because I'm not familiar
  enough with SSL certificates. I assumed it meant structurally valid,
  like, not just plain giberrish, but a well-formed certificate, even

- Now that I understand how this feature works, I think it would make
  sense to activate it (tick the checkbox) by default. Having to opt-in
  gave me the feeling I was doing something potentially slightly

Anyway, thank you Paul for the explanation.

Have a nice day.
