Replace the "sendmail" command in your filter script with a command line SMTP program such as mini_sendmail, and deliver your filter output to a separate smtp listener -- maybe port 10028 -- with "-o content_filter=" Other possible solutions include using multiple postfix instances, or using amavisd-new as your content filter, which has (some) support for altermime. -- Noel Jones > > Hope of inspiration from the list... thank you! > > > Klaus. > > p.s.
