Hello All , I am having a bit (to put it mildly) of trouble with trying to create two systems . One which users will have access to external email & internal , the others will have access to internal only . my setup is something like this . all ip's are fictitous . ------------------------------------- ------------------------- | | | | | [ inside ] [ in&out ] [ router ] [ The World ] ( smart host ) 10.0.0.1 199.33.245.7 Not Routeable Routeable - 'inside' can send email to 'in&out' . - 'in&out' can send email to 'inside' . - 'in&out' can send email to 'The World' . - 'The World' can send email to 'in&out' . - 'inside' cannot send email to 'The World' . - 'The World' cannot send email to 'inside' . - All users must have addresses in the same domain . ie: joe@ficticous.com At present: - 'in&out' is the primary (smart) mailer for the domain . - 'inside' points all mail that it doesn't know how to handle to the smart host 'in&out' . I have tried several sendmail 'access' database permutions on the 'smart host' to no avail . If I attempt to reject mail from 'inside' it can nolonger send email to 'in&out' . You can guess how the rest of the permutations I have tried have gone . Any helpful insights are welcome . Tia , JimL +----------------------------------------------------------------+ | James W.
