Another possibility is that Berkeley DB returns an ENOENT error for
reasons other than that the file does not exist.
For example, I recall that an early version of ReiserFS returning
ENOENT errors on an open file handle because they could not find
something. In that case, the OS kernel returned an ENOENT even
though the file could be opened.
However, if "postmap -s /etc/postfix/virtual" can "read" the file
as root, but smtpd cannot open the file as root before it drops
privileges, then I suspect a "security" configuration error, like,
perhaps SeLinux is not turned off after all.
Look in your system/security logs.
