Hi, I've been using SOGo webmail together with Postfix and Dovecot for a little over a year now. When I first set it up, I verified that I could use it together with my S/MIME certificate, and it worked fine.
When testing it today, I noticed that I can not read S/MIME encrypted mail that I have received. Instead, SOGo webmail just shows me a mail with an smime.p7m attachment. If I click on the "View attachment" button, I get the error message "An error occurred during object publishing. Did not find mail method or part-reference!" I can download the attachment by clicking the download button. I am also able to successfully send an S/MIME signed mail from SOGo to another mail account, so I know for sure it is finding my private key. I can also send an S/MIME encrypted mail to another mail account. If I look in /var/log/sogo/sogo.log when opening the encrypted mail, this is what it says: ---- Jan 10 16:34:07 sogod [1413]: [ERROR] <0x0x563d0bcaeef0[UIxMailRenderingContext]> found no viewer for MIME type: application/pkcs7-mime Jan 10 16:34:07 sogod [1413]: [WARN] UIxMailPartLinkViewer No path specified, returning first part Jan 10 16:34:07 sogod [1413]: [WARN] UIxMailPartLinkViewer No path specified, returning first part Jan 10 16:34:07 sogod [1413]: [WARN] UIxMailPartLinkViewer No path specified, returning first part Jan 10 16:34:07 sogod [1413]: [WARN] UIxMailPartLinkViewer No path specified, returning first part Jan 10 16:34:07 sogod [1413]: [WARN] UIxMailPartLinkViewer No path specified, returning first part Jan 10 16:34:07 sogod [1413]: 10.11.12.2 "GET /SOGo/so/per/Mail/0/folderINBOX/87095/view HTTP/1.1" 200 1333/0 0.045 - - 0 - 14 ---- I am using SOGo version 5.9.1. There are 4 sogod processes running on the server, which is running Ubuntu 22.04.3 LTS (jammy). Tried searching the mailing list archives for something similar, but no luck. The only thing I could find was https://bugs.sogo.nu//view.php?id=5450 but I started using SOGo after that change was made. Any hint on where to start looking would be very helpful. Thank you.
