[MlMt] MM mishandling subject of a reply to a forwarded message

[Eric Sharakan]

Hi, I have a message that was forwarded by me initially, so the subject has the form "Fwd: XXX" where XXX was the subject of the original message before I forwarded it.

If I attempt to send a reply to that message, MM adds "Re: " to the start of the subject, but it also removes the "Fwd: " prefix, so now the subject looks like "RE: XXX".

Now when I hit send, I get an error complaining that "The subject of the original message was changed in your reply".

This is running version 6223 on Sequoia 15.3.

Have others seen this?  Benny, is this a known issue?
