Without further commenting on your approach, I can see that in the conditional assignment i<e will always be FALSE as e is undefined thus zero.

Actually I can't see the advantages of using sprintf, so why do you insist on it?

qmail-users

qmail-users(5)                                                  File Formats Manual                                                 qmail-users(5)

NAME

       qmail-users - assign mail addresses to users

OVERVIEW

       The file /var/lib/qmail/users/assign assigns addresses to users. For example,

          =joe.shmoe:joe:503:78:/home/joe:::

       says that mail for joe.shmoe should be delivered to user joe, with uid 503 and gid 78, as specified by /home/joe/.qmail.

       Assignments  fed  to  qmail-newu  will  be  used  by  qmail-lspawn  to  control  qmail-local's deliveries.  See qmail-newu(8).  A change to
       /var/lib/qmail/users/assign will have no effect until qmail-newu is run.

STRUCTURE

       /var/lib/qmail/users/assign is a series of assignments, one per line.  It ends with a line containing a single dot.  Lines must not contain
       NUL.

SIMPLE ASSIGNMENTS

       A simple assignment is a line of the form

          =local:user:uid:gid:homedir:dash:ext:

       Here  local is an address; user, uid, and gid are the account name, uid, and gid of the user in charge of local; and messages to local will
       be controlled by homedir/.qmaildashext.

       If there are several assignments for the same local address, qmail-lspawn will use the first one.

       local is interpreted without regard to case.

WILDCARD ASSIGNMENTS

       A wildcard assignment is a line of the form

          +loc:user:uid:gid:homedir:dash:pre:

       This assignment applies to any address beginning with loc, including loc itself.  It means the same as

          =locext:user:uid:gid:homedir:dash:preext:

       for every string ext.

       A more specific wildcard assignment overrides a less specific assignment, and a simple assignment overrides any wildcard  assignment.   For
       example:

          +:alias:7790:2108:/var/lib/qmail/alias:-::
          +joe-:joe:507:100:/home/joe:-::
          =joe:joe:507:100:/home/joe:::

       The  address  joe  is  handled  by the third line; the address joe-direct is handled by the second line; the address bill is handled by the
       first line.
