Sending bandwitdh can be reduced by using BCC instead of the IMAP append to the sent mailbox.
Can you elaborate on this?
I would have thought that the IMAP Append command would *save* bandwidth (as opposed to having the client save a copy to the Sent folder, thereby uploading the full message a second time).
This is exactly, what IMAP APPEND does: The client uploads the message via SMTP first and via IMAP a second time.
If you add a BCC recipient to each message, that is placed by SMTP into the Sent Folder, and disable the IMAP save, you upload the message just once. How you can do this, depends on your SMTP framework. Many people use subaddressing or detail:
address+detail@example.org

BTW: There is another annoyance with a limited bandwidth, when you compose a message, MUAs autosave the message into Draft in regular intervals.
