Looks like plain old inline PGP. Does GpgOL even support inline PGP?

• ebo added a comment.Tue, Apr 15, 10:13 AM

Yes. I did only one test though, with an inline PGP mail sent with Claws.

• werner added a comment.Tue, Apr 15, 10:13 AM

Yes it does. I even tested it yesterday.

turned out that not the flowcrypt encryption is the issue here. The cause seems to be the usage of Proofpoint "Email Warning Tags".

Any software which inserts a banner or otherwise changes the mail structure will cause problems with GpgOL and has a high probability of making parallel usage impossible.
