    It seems that some exim mail servers implement sender verify callout and when my clients send mails to users on these servers the mails do not reach them.


    They instead get a bounce back informing them
    Remote host said: 451 Could not complete sender verify callout

    Does any know how to resolve this on a plesk 8.+ server...?
