You might as well put it through mixcvt.  It won't make matters any worse. 
The message will be as readable in the copy as it is in the one with the 
600MB file.  What's more, the annoying warning won't occur in the copy.

Since you don't have the original mailbox any more, there's no point in 
worrying about it.  If the user hasn't complained about that message being 
truncated by the bug by now, s/he probably won't ever complain.

For the record:

The bug, which was fixed in January, only impacted godzillagrams.  The 
message had to be at least 64K; messages less than 64K were completely 
immune to the bug.

Specifically, if (size MOD 64K) < (size / 64K), then (size MOD 64K) bytes 
got truncated.

For example, with a 10MB message, a message from 10,485,761 to 10,485,919 
bytes would be truncated to 10,485,760 bytes, and a message from 
10,485,920 to 11,534,336 (11MB) would be immune.

It really was a rare bug.
