Just a quick request for advice on filtering incoming email. About 12+ years ago on a system which has long since retired, I remember having a problem with WINMAIL.DAT attachments in emails. The solution used some combination of tools which, from memory, included things like tnefclean and mmencode. It would process email on the way into the server and sanitize it before delivering to the recipient's inbox.
Some broken email clients can make a mess of attaching certain files which other clients then cannot open. I was thinking of doing something similar to the above (re-encode mime attachments) now but I'm not sure what the best way of handling this is. Any advice appreciated. Thanks.
