title: Edit Raw Message on IMAP Server
body: <p>Is there a way to edit the raw contents of a message with some API in Perl, Python, or even Ruby?  A quick Google search showed me little.  In short: someone sent me a message a long time ago with the wrong timestamp, and it shows up at the top of folder in Thunderbird.  This has annoyed me for a while, and I want it to be sent from the proper year (2010), not from the future (2020).  To be clear, headers show right date and times.  The other's client clearly did this, so it should require minimal effort? Right?</p>
