Hello Stanislas,

All of this sounds a bit "bizarre", not to say frightening...
To avoid any ambiguity, could you post the output of doveconf -n?
As well your encryption and decryption scripts?
And tell us how postfix is configured wrt LMTP?

There could perhaps be a (temporary) workaround at Postfix's level, by limiting the number of recipients?
