As far as I can tell, no. > Question 2: Could the config be corrected to process 7z attachments > correctly? You could give 7zip [1] a try. According to [2], 7zz integration does not need code changes. You'd have to deploy 7zz manually, though, as I don't see it in EPEL either. > As a final note: I was misled by the fact that in the mail headers the > mail was reported as scanned and not as undecipherable. > > X-Virus-Scanned: amavisd-new at noa.gr > > Question 3: How can we configure amavis to report such mails (which > failed to open for scanning) as undecipherable? You can't. This particular code path does not add the undecipherable flag. [1] https://www.7-zip.org/ [2] https://gitlab.com/amavis/amavis/-/merge_requests/90
