You may enable archive quarantine in your pre-queue amavis, e.g.: $archive_quarantine_method = 'local:archive-%m'; $archive_quarantine_to = 'archive-quarantine'; # default to be able to compare a corrupted message to what was seen by amavisd. This would not help if a problem lies in stages prior to or in amavisd, but at least it can help troubleshooting later stages (SMTP output from amavisd and apache-james). Mark
