Problem with digitally signed attachments.

1

When I send or receive mail with attachments digitally signed, the mail, sent or received, do not allow opening attachments, which are with a .txt extension instead of .pdf.p7m.
Why? And What is the solution?

Hello,

could you send me one of these faulty emails saved as .eml?
right click on it - save as .eml and send me it to [email protected] together with this topic’s address: https://discourse.emclient.com/emclient/to…

Hi, it was most likely bad certificate. Which one do you use, is it free or paid so I could retest it?

The extension .p7m it’s added to any documents signed with the most used software in Italy DIKE https://www.firma.infocert.it/install… .
The software is free and is recomended from the financial autority and 80% of the Italian company use this solution to digitaly sign the document .pdf .xls .doc etc.
If you need a file .p7m i can send you a copy, let me know.
