Problem with piping email into script on CentOS using /etc/aliases or .forward

I need to use this functionality tomorrow, and am still having issues with it. </panic> </slapForehead> Any assistance would be much appreciated.

I added to /etc/aliases:
tp: "|/raid/home/mdarling/code/sms/sms > /raid/host/toadprinceillustrations.com/logs/tp.log 2>&1"

And, of course, ran newaliases after to regenerate aliases.db.

If I run "mail tp", with test as subject/body, it's like the email goes nowhere.


To try to diagnose the problem down, I:

* Recompiled the c plus plus (experts exchange wont let me use plus signs here for some reason) program sms so the only instruction is "cout << 10 / 0;", which when ran adds a line to dmesg like: "sms[12602] trap divide error . . ." to I can easily see if the program executes, without the possibility of a bug in my program causing it to appear like the email isn't going anywhere. If I "mail tp", a divide error isn't added to dmesg. (I've also tried the program as originally made without the divide by zero instruction -- which works correctly when executed normally not through an email pipe -- and it doesn't seem to execute either, just in case dmesg wouldn't log a divide by zero error for some reason through an email pipe.)

* Made sure there aren't any conflicting entries in /etc/mail/virtusertable, and ran make in that directory to regenerate virtusertable.db.

* Removed the tp line in /etc/aliases, and mailed tp. The email properly arrived in /etc/mail/tp, so I know there isn't a general configuration issue with the account or sendmail in general.

* Removed the tp line in /etc/aliases, and created ~tp/.forward with:
"|/raid/home/mdarling/code/sms/sms > /raid/host/toadprinceillustrations.com/logs/tp.log 2>&1"

which I'm not sure should work, but I saw some references to using .forward instead of /etc/aliases to pipe email. Had no effect here either.

I haven't changed any of the file permissions or ownerships, but ownershio/permission-checks so you can see them are:

Thanks, you pointed me to the solution.  Switching to user tp, I couldn't execute /raid/home/mdarling/code/sms/sms, I got permission denied.  Had to chmod 755 ~mdarling, now it works.  By default, it was 700.  I'm the only person who has access to the server, so I'm fine with 755 permissions here.
