my @input = <DBLIST>;
foreach (@users)

mu-mkdir
MU-MKDIR(1) General Commands Manual MU-MKDIR(1)NAME
mu_mkdir - create a new Maildir
SYNOPSIS
mu mkdir [options] <dir> [<dirs>]
DESCRIPTION
mu mkdir is the mu sub-command for creating Maildirs. It does not use the mu database. With the mkdir command, you can create new Maildirs
with permissions 0755. For example,
mu mkdir tom dick harry
creates three Maildirs, tom, dick and harry.
If creation fails for whatever reason, no attempt is made to remove any parts that were created. This is for safety reasons.
OPTIONS
--mode=<mode>
set the file access mode for the new maildir(s) as in chmod(1).
