Something new about "XGE-15978: Outbound SMIME signed mails intermittently failing verification at recipient"?

Question

Hi there, 
 Does anybody know any suggestions, recommendations or workarounds from sophos about this annoying bug? 
 It's known for month and nothing happens. 
 Thanks. 
 Chris

Hello there, 
 Thank you for contacting the Sophos Community. 
 Do you have a Case ID? There is a Flag development that can turn on that makes smime signature getting validated successfully for outbound emails at the recipient end. 
 If you don't have a case open I would recommend you to open one and mention XGE-15978. 
 Regards,
