Hello atomheart, SmimeCapabilities is an attribute (optional) in S/MIME signed messages. The Bat! doesn't include it. The Bat! doesn't delete or damages S/MIME certificates. Please attach a few S/MIME signed messages made by Outlook in https://www.ritlabs.com/bt/view.php?id=60, so we will modity The Bat! to also include SmimeCapabilities in messages signed by The Bat!
I don't know why does Outlook use 40-bit encryption for messages without the SmimeCapabilities attribute. -- Best regards, Maxim Masiutin Managing director Ritlabs S.R.L. ________________________________________________________ Current beta is 5.2.1.1 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
