3.15 Re-sending messages

You may occasionally wish to send messages modifying the header of a message.

For instance, you may want to send a message with the same body to multiple receivers independently. Please imagine the case where you put a created message destined to Pooh in +queue and then you wish to send an another message to Piglet by copying it and modifying its header. Let's call this recycle sending.

Also, you occasionally wish to send a message adding the Resent-To: field to a target message. This is a kind of forwarding. This is called header conversion because a message header is modified. The forwarding described the previous subsection is called encapsulation because a message is embedded into another new message.

Header mode exists for this reason, modifying a part of the header, sending/queuing the created message. You can think this is a kind of Draft mode which prohibits modifications of its body.

The following commands are provided in Summary mode to enter Header mode.

‘W’

Recycle sending. Enter Header mode in order to modify To:, Cc:, From: of a target message. Typical usage is for messages in +queue or +postq.

‘r’

Re-sending. Enter Header mode in order to add Resent-To:, Resent-Cc:, Resent-From: of a target message. Re-sending may confuse receivers, so you should think carefully before using it.

In Header mode, you can make use of completion and circular completion like in Draft mode. When you are finished inputting the header, send the message using one of the following commands. You may be concerned because the body of the message is not displayed in your new message. But you need not worry, since the body and a part of the target message is certainly used.

‘C-cC-m’

Compose a message, put it into +queue or +postq, and let it be waiting to be sent.

‘C-cC-c’

Compose a message and send it. You are asked, "Really send this message? (y or n) ". Type ‘y’ to send it.
