I'm curious as to why you believe this to be the case. I just sent myself
two messages using Outlook (a client with rather high use in business
emails...), one with my address in Cc: and one with it in Bcc:. In both
cases there was no To: header and in the Bcc: case no Cc: header either.
Sending emails with all the addresses in Bcc: is not unusual and not just
for legitimate 'marketing' emails. Think of an organisation running a
training course sending joining instructions to all delegates for example.
I also checked with the alpine client and again there is no To: if Cc: is
present. If Bcc: was the only recipient field used then by default alpine
does add a To: undisclosed-recipients:; header but that can be switched
off.
Oh and this message nearly ended up with only a Cc: header as I did
reply-all which on alpine puts the original sender in the To: field and
all other addresses (i.e. the list in this case) in Cc:. I then removed
your direct address as you are on the list. While writing the message I
realised that perhaps I had better move exim-users to the To: line for
this particular situation!
