Ralph already answered this, but I will note that when you're using the "sendmail/pipe" interface you're accepting reduced functionality and this is part of it (also, you cannot use Dcc: when using sendmail/pipe or a traditional MH-blinded group address, so I'm not even sure how you would use this in practice unless you just stick to the MH-style Bcc). If you're not using sendmail/pipe, this shouldn't be an issue. --Ken -- Nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
