"Q-S doesn't work with Vpopmail Vpopmail basically strips out environment variables set within the tcpserver SMTP rules file - specifically the QMAILQUEUE environment variable. As it is responsible for starting qmail-smtpd, that means Qmail-Scanner never gets called. This is really a bug with Vpopmail, but a workaround is to set QMAILQUEUE within /service/smtpd/run instead.(..)"
This "bug" has been fixed in some recent version of vpopmail?
