  Log Message:
  -----------
  lib-lda: Do not convert "From:" message address to STMP address, just to make a string for logging.

This leads to problems when the message address (RFC5322) has UTF-8 code points
in the local part, which is (currently) allowed for message addresses, but not
for SMTP addresses (RFC5321).
