Bounced email checker

Bounced email checker has a problem with some emails:

Message: 'ansi_x3.110-1983' is not a supported encoding name. For information on defining a custom 
encoding, see the documentation for the Encoding.RegisterProvider method.
Parameter name: name

Exception type: System.ArgumentException
Stack trace: 
at System.Globalization.EncodingTable.internalGetCodePageFromName(String name)
at System.Globalization.EncodingTable.GetCodePageFromName(String name)
at System.Text.Encoding.GetEncoding(String name)
at OpenPop.Mime.Decode.EncodingFinder.FindEncoding(String characterSet)
at OpenPop.Mime.MessagePart.ParseBodyEncoding(String characterSet)
at OpenPop.Mime.MessagePart..ctor(Byte[] rawBody, MessageHeader headers)
at OpenPop.Mime.Message..ctor(Byte[] rawMessageContent, Boolean parseBody)
at OpenPop.Pop3.Pop3Client.GetMessage(Int32 messageNumber)
at CMS.Newsletters.Extensions.Pop3ClientExtensions.GetSafeMessage(Pop3Client pop3Client, Int32 
messageNumber)

Any Idea how to resolve it?

It is probably a problem with bounced email encoding. There is Check bounced emails scheduled task, which runs once per hour by default. The class responsible for it is CMS.Newsletters.BounceChecker, in there we have an a event OnFallbackDecoderEvent - which occurs when a character set from email content type header could not be mapped to the encoding. This allows to map given character set name to the encoding manually. I would raise this issue with support and ask them if it is possible to attach your custom handler to this event.

Any news on this. We have a lot of such error messages in an event log.
