SOO IL KIM - 10-Sep-2007 05:51 That's was my initial thought/guess of BCC when we talked about hiding others' email address from the message header of the client/recipient's inbox. There are couple of options we can choose: 1) Use CC or TO instead of BCC. In this option, anybody in CC or TO will see others' email which would not be what the sender want. 2) Refactor Mailtool.processSendEmail() to send bulk message into several message transactions as many as the size of recipients. That would slow down the mail-sending when the size of recipients is large. Any other idea?

Jason Shao - 10-Sep-2007 07:36 #1 seems problematic -- our interpretation of FERPA (in the US) is that this could be considered a violation. In addition, many of our professors are intersted in sending out "you did poorly on the last test, want extra help?" type messages and I think hiding all the recipients of that category of notification is desireable. #2 performance doesn't worry me much -- especially if we're talking a clustered configuration where your instances can spread the workload. The main problem I could see with this is we now have many possible failure modes -- e.g. how do we handle/display a partial failure?
