Preserve Formatting in mail messages

[ila]

Hi ,

I am trying the output of my program as an email . the output looks like

Table output
--------------------------------------------------------------------------

MMMM 05.5 P 16 -99.00 NULL
MMMM 2110-09-48 55 P 12 -99.00 NULL
MMMM 2110-09-48 50 P 10 -100.00 NULL
MMMM 2110-09-48 55 P 11 -100.00 NULL

Basically everything aligned on right side of column wise when I output to a file. However when I use (this editor is messing up formating)
> cat tableoutput.txt | mail -s "Table Output" email address

The message I receive is

Table output
--------------------------------------------------------------------------

MMMM 05.5 P 16 -99.00 NULL
MMMM 2110-09-48 55 P 12 -99.00 NULL
MMMM 2110-09-48 50 P 10 -100.00 NULL
MMMM 2110-09-48 55 P 11 -100.00 NULL

Is there a what ensure that the above format is preserved. (this is the format in which i receive the email)

Thank you for your help,
Ila
