Hi Can ask a quick question on this When I create a new user on my server (the e-mail users do not have local accounts) I put the username in file named after the domain in a directory called virtuals
the exim router does a check against the local parts and if the user exists in the file under the relevant domain it passes it then when it delivers it in the transport a new folder is created by exim for that user I have not had to create the folder in advance PS I do not have many users so this manual process works for me it would be no fun for you guys with hundreds or thousands I guess you would have databases to search Regards Hill ----- Original Message ----- From: "Marc Perkel" <[EMAIL PROTECTED]> To: "Stuart Gall" <[EMAIL PROTECTED]> Cc: "exim users" <[email protected]>; "Martin A.
