Hi,
I stumbled upon the "Claws Mail leaks plaintext of encrypted
emails to IMAP server" article[1].
The corresponding bug task[2] is marked RESOLVED FIXED, so I
assume the article no longer applies and I suggest that the
article is updated to make this immediately clear (maybe an
information box at the beginning?).
Cheers,
Nathan
