If a mail contains a .p7m file attachment, all further attachments (in order of the mail parts) are not displayed.
Two examples (KMail with correct structure in order, Outlook with missing attachments):
| KMail | Outlook | |
| 1 |  |  |
| 2 |  |  |
Setup
- I prepared a tarball with all neccessary files (eml, msg, screenshots, gpgol log):
- The keyring contains the usual test certs + alice and bob
- The p7m is encrypted for Berta (but it does not matter, if the private key is in keyring or not)
Log
After encountering the p7m attachment, the gpgol log file shows repeatedly for all attachments:
