message: Wide Reply
1.4 Wide Reply
==============
The ‘message-wide-reply’ pops up a message buffer that’s a wide reply to
the message in the current buffer. A “wide reply” is a reply that goes
out to all people listed in the ‘To’, ‘From’ (or ‘Reply-to’) and ‘Cc’
headers.
Message uses the normal methods to determine where wide replies are
to go, but you can change the behavior to suit your needs by fiddling
with the ‘message-wide-reply-to-function’. It is used in the same way
as ‘message-reply-to-function’ (Reply).
Addresses that match the ‘message-dont-reply-to-names’ regular
expression (or list of regular expressions) will be removed from the
‘Cc’ header. A value of ‘nil’ means exclude your name only.
‘message-prune-recipient-rules’ is used to prune the addresses used
when doing a wide reply. It’s meant to be used to remove duplicate
addresses and the like. It’s a list of lists, where the first element
is a regexp to match the address to trigger the rule, and the second is
a regexp that will be expanded based on the first, to match addresses to
be pruned.
It’s complicated to explain, but it’s easy to use.
For instance, if you get an email from ‘foo@example.org’, but
‘foo@zot.example.org’ is also in the ‘Cc’ list, then your wide reply
will go out to both these addresses, since they are unique.
To avoid this, do something like the following:
(setq message-prune-recipient-rules
'(("^\\([^@]+\\)@\\(.*\\)" "\\1@.*[.]\\2")))
If, for instance, you want all wide replies that involve messages
from ‘cvs@example.org’ to go to that address, and nowhere else (i.e.,
remove all other recipients if ‘cvs@example.org’ is in the recipient
list:
(setq message-prune-recipient-rules
'(("cvs@example.org" ".")))
If ‘message-wide-reply-confirm-recipients’ is non-‘nil’ you will be
asked to confirm that you want to reply to multiple recipients. The
default is ‘nil’.
