Thanks Milan,

No, its not currently fixed width. I don't have any control over the
source data being uploaded (as I would lose all the performance gain
in trying to pad the data anyway). What is the impact of using a
non-fixed width file here?

The file, for example, looks like this:

jsmith@...
benedict@...
bill@...

etc.
