When mail
needs to know the sender of a message, it
looks it up in one or more headers of that message. Such headers
constitute a sender list. The first header from the list
that is present in the message and has a non-empty value is used.
If none is found or if the sender list is empty, the value of the
message envelope is used.
The commands sender
and nosender
manipulate the sender
list.
If the command sender
is used without arguments, it displays
the contents of the sender field list. If arguments are given,
each argument is appended to the sender field list. For example:
? sender Sender address is obtained from the envelope ? sender mail-followup-to reply-to ? sender mail-followup-to reply-to ? sender from ? sender mail-followup-to reply-to from |
Command nosender
is used to remove items from the sender
field list:
? sender mail-followup-to reply-to from ? nosender reply-to ? sender mail-followup-to from |
When used without arguments, this command clears the list:
? nosender Sender address is obtained from the envelope |
