Hi Guys, Tearing my hair out here trying to solve this one. I know it's supposed to be a permissions issue but bear with me first please. variable.php: $mailroot = "/home/exim4u/mail/"; Permissions are set to exim (UID / GID 93) for the above directory: drwxr-xr-x 3 exim exim 4096 Oct 28 13:32 . drwxr-xr-x 6 root root 4096 Oct 28 13:32 .. drwxr-xr-x 3 exim exim 4096 Oct 31 12:25 mail I create a domain eg domain.tld. System UID and GID are set to 93. Domain mail directory appears as /home/exim4u/mail/ which I believe is correct as it should then create /home/exim4u/mail/domain.tld for the mailboxes. However, it doesn't create the folder and this is what I see in exim/main.log: 2013-10-31 13:35:55 1VbqXb-0004fN-Is == /domain.tld/postmaster/Maildir <postmaster(a)domain.tld> R=virtual_domains T=virtual_delivery defer (13): Permission denied: cannot create /domain.tld/postmaster/Maildir I've been struggling to figure out why it's not creating /home/exim4u/mail/domain.tld with no success, even manually creating the domain.tld directory under /home/exim4u/mail. I then decided to create /domain.tld off the root since that appears on the surface to be what it's actually trying to do! Guess what, the mail got delivered and the postmaster directory created as /domain.tld/postmaster/Maildir. Why is it trying to create the directory off the root and not under the correct mailroot directory?
