Re: [Evolution] Bcc exposes recipients

["Arthur S. Alexion" <arthur alexion com>]

My mistake -- I hope.  In the event that there are no recipients in the
To: or CC: fields, Pegasus warns you that you have not designated a
recipient beyond the BCC, and asks if you want to send anyway.  If you
reply yes, it just sends one message.

What happens with Evolution and the exposing servers when there are
recipients in the "visible" to: or CC: fields?  Is the Apparently-to:
header added in that instance?

When you address a message in Pegasus offline, only one message is
visible in the outbox queue.  When you go online and send the queue, the
mailer generates separate messages for the visible recipients and for
the blind recipients.  I believe that all blind recipients get the same
message, and I never rely on a BCC recipient not knowing the other BCC
recipients, though that may be the case.  I believe that there is a
setting on whether the BCC field is displayed on the BCC copy, but its
been a long time since I checked that option.
