    Changing 550 <>... User unknown error

    I am trying to change the default error message when a users email account doesn't exist on our Linux mail server.

    so instead of 550 <>... User unknown error message


    something like 550 <>... User unknown, please email, Thanks

    I don't know Linux to well, just how to logon, navigate around directories and edit text files (using VI). We are a small company with only 12 people and the mail server uses
    Red Hat Linux 5.2 (Apollo) 2.0.36

    Take it this 550 error message is in a text file somewhere??

    Thanks for any help..

    Just realised that the mail program used is SendMail therefore will move this to SendMail forum.

    Also can anyone tell me how to change the limiting size of outgoing emails? Our ISP sad that the limit is 5Mb maximum email size but we can only send about 3Mb maximum so take it that the Linux mail server is restricting this. (maximum message limit exceeded message)
