Hello, normally on an Apple Device (Ipad, Iphone) a signed incoming mail is shown with a small black icon with an arrow. If i sent a mail with a valid cert trough the gateway the message in the inbox will not have this icon, but clients like outlook or gmail says that the mail is signed correctly. If i import the cert to my client and send the same mail with client-side-signing the black icon is showing. Is there any setting at the gateway which will make the trouble, maybe use another signing algorithm or anything else ?
Thank a lot for any helping, Patrick
