Yes, they are uploading even full iso images with 4,7 GB as email attachments. :-/ Which means, that SOGo will use up to 8 GB for MIME/base64 encoding it in RAM! We had several of those already. When on a slow line, those uploads will break before finished and leave those OGo* files behind. Because of that we asked Inverse for upload limits. Check WOMaxUploadSize and SOGoMaximumMessageSizeLimit.
