hi,
i'd like to be able to send an email to a number of people without sharing the
addresses in the To: or Cc: headers. i can do that with Bcc: but i'd like the
people to note that the mail is for them personally. and not something copied
to them as fyi.
so what i would like to do is to have a mail sent to each recipient separately,
with their own address on the To: field.
greetings, martin.

Hello Martin,
That's an interesting use case. Just out of interest, is there an
MUA/MTA out there that does it ?
There is a "sendmail" hook that takes the message object to be sent [1]
and does whatever logic to actually handle delivery of said message.
You can write a hook that loops over the addresses in Bcc and sets the
addresses as a recipient before shelling out to sendmail/msmtp/your MTA
of choice. Very roughly, something like that (untested):
```
# The hook is responsible for _all_ sendings, so we also need to manage
# the "standard" sendings
bcc = message.bcc
message.bcc = []
IO.popen("msmtp -t --read-recipient-from") {|p| p.puts message}
# We need to save anything we modify, because we will put it back at the
# end so that sup saves a relevant message internally
to = message.to
cc = message.cc
# A specialized message, only for (each of) you
message.to = []
message.cc = []
bcc.each do |recipient|
message.to = [recipient]
IO.popen("msmtp -t --read-recipient-from") {|p| p.puts message}
end
message.to = to
message.cc = cc
message.bcc = bcc
```
As I write this, I realize that messages can't be encrypted to the
specified email address. To people more familiar with hooks: I don't
presume methods in the Redwood module are available ? Is it possible to
call CryptoManager.encrypt in a hook ?
