Error with MailMessage.Load with new version of Rebex.Mail

Question

Hi,
since I have updated Rebex.Mail to version 6.0.8372 I have started having problems with the mail load, for some mails the command Rebex.Mail.MailMessage.Load(byte[] data) returns an exception

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=Rebex.Mail

I did several tests with previous versions and noticed that the problem occurs starting with version 6.0.8314.0, version 6.0.8295.0 works correctly

Answer 1

Thanks for bringing this to our attention! It looks like the "workaround for yet another form of wrong Content-Disposition parameter encoding" (introduced in 6.0.8314) is triggering this error due to a bug. Apparently, the code is unable to handle some forms of wrongly-encoded MIME parameters. We will fix this for the next release. If you would like to get a hotfix in the meantime, please let me know.
