Unfortunately no. I have munge8bit enabled which means for example german
umlauts are converted to 'X'. But that doesn't affect envelope MAIL FROM
addresses. cyrus lmtp simply rejects those mails.
That's exactly my question, should cyrus lmtp be more liberal with sender
envelope addresses (it can be strict with RCPT TO of course)?
