I doubt this is a high priority.

It looks like the source of the problem here is that the encoding that the mail client specified isn't a standard one. Specifically, it mentions "windows-874" when it looks like the appropriate one is "cp874". We can create our own encoding alias table for these mappings, or we can try a strategy of replacing the encoding names, since it looks like the aliases form a pattern:
encoding.replace("windows-", "cp").

The replace idea might prevent some future problems, but I'm not 100% sure that it won't introduce its own side effect. The lookup table is more explicit but requires us to react to errors as they come in. That being said, I don't think we're getting a flood of these errors all with different unknown encodings, so it's probably sufficient anyway.
