Title: #179 fix to-other cc-self issue when using gmail smtp

Remove extra transaction when sending to & cc since a separate transaction only necessary for bcc.
This fixes an issue where sending to another address and CC-ing yourself would cause the message to NOT go into your inbox when using Google's SMTP. This seems to be a bug in Google's smtp, but doing a single transaction for both to and cc fixes the issue (not to mention making it more efficient)
