Nevertheless we have had problems of malware sending to -REQUEST addresses from phony accounts, and having the automated response then bounce. Of course this was a problem BEFORE malware. That's why we have out lists with ATTACHMENTS= NO LANGUAGE= NOHTML SIZELIM= 250 (whatever) Now that's not to say that this is bullet-proof, but so far, it has really helped. /Pete
