I actually installed nmh from scratch to reproduce the bug before
writing up the report, so there shouldn't be anything special in there,
but sure:

lambda@hdev:~$ cat .mh_profile
MH-Profile-Version: 1.0
Path: Mail

lambda@hdev:~$ cat .mh_profile
MH-Profile-Version: 1.0
Path: Mail
lambda@hdev:~$ cat /etc/nmh/mts.conf
# nmh mail transport interface customization file.

# Check the mh-tailor(5) man page for descriptions of available options.

# The delivery method to use, which must be one of the following:
# smtp:          nmh opens a socket connection to the appropriate port
#                on the servers listed below and speaks SMTP to the
#                first one that responds.  This is the default.
# sendmail/smtp: nmh pipes messages directly to the sendmail program,
#                speaking SMTP.  Can be abbreviated to "sendmail".
# sendmail/pipe: nmh pipes messages directly to the sendmail program,
#                using the -t option so that addresses are retrieved
#                from the message.
mts: sendmail/pipe

It is implied in the description of the dcc header.

Thanks for the info. I guess this explains why I vaguely remember bcc
working in the past.

Thanks again, I'd have totally missed that. Sometimes it is hard to
know which man pages to read ... :)

Thanks for your help,
Harald
