It was caused by a message from Thorsten.  Gandi Mail have frequently
been rejecting Thorsten's messages, with the following reason given:

  Reject for policy reason. RULE2_1: Message detected as phishing either
  by heuristic analysis or through a fraudulent link found in it.

Other Gandi Mail users have had their subscriptions auto-disabled as
well, including shortly after you reported that they had claimed to have
fixed the issue.  I see no evidence that they fixed it.
