    It seems that all implementations of Qmail on Plesk servers are allowing email to APPARENTLY be relayed if the email address in the RCPT TO: contains an address like spamtest%abuse.net

    It correctly rejects relaying (we have SMTP AUTH) if the address is of a standard someone@somwhere.com, but seems to indicate via a 250 response that it has successfully relayed when the address is someone%somewhere.com

    Because of thsi our servers are getting blacklisted as open relays on ordb.org and several other sites.

    Does anyone know how to fix this?
