as i wrote before sender "<>" is mailer daemon dont do it anything against it if the content is spam then the client may have been infected so drop him in total, second alternative stop his spam going outbound with some content filter like amavis etc, in any case inform him that he might got infected, or have some missconfigure , sometimes some anti/spam virus software likes to inform the mostly faked sender that his mail may was stopped filtered or not delivered by spam tag, this is a totally missbehave going outbound Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Joerg Heidrich
