grep simply deals with whatever input you give it, in this case, the
output of the ps program. the output of ps varies, depending on the
dimensions of the terminal - on a standard console this might be 80x25.
i suspect that grep isn't "seeing" the string mailsmsgateway in its
entirety, because depending on things like start time, pid, and username,
it might not fit (in its entirety) in your window. to get the full output
of ps, add 'ww' to your command.
-w Use 132 columns to display information, instead of the default,
which is your window size. If the -w option is specified more
than once, ps will use as many columns as necessary without re-
gard for your window size.
so in effect, ps auxww will do what you're after.
