Zip file attached to email corrupted
We are using SendSimpleEmail activity with SendAllAttachments parameter set to true to send emails with case attachments.
It works correctly with different kind of attachments (images, pdf, docs..) except for .zip files which are sent corrupted.
The attachment can be correctly downloaded from the work item and opened, so it is saved correctly in Pega repository. Probably there is an issue when attaching it to the email.
Is there anything we can configure to avoid the issue?
