Agreed (although - most users will send Windows attachments ;-). Anyway, for that purpose, a regular expression like: \.[a-zA-Z][a-zA-Z0-9]{0,3}\.(vbs|pif|scr|bat|com) Will do it. Amavisd-new has a nice default example for this. Regards, Bojan Zdrnja _______________________________________________ Full-Disclosure - We believe in it.
