Hi, After some openssl update (from Ubu 18.04 to 20.04) the crypt() function does not accept special chars in salt anymore. Very old mail passwords still have (random) the '+' in the salt - this passwords does not work after Update I could not find any dovecot / openssl / linux way to tell openssl/dovecot to accept this special chars in the salt. Anyone know a trick about this? I don't have the clear text passwords and there is no way to decrypt it (Only way is tell the customer to change there password). thx
