How does PMMail invoke your REXX script? MR/2 invokes the presend script
synchronously, so an delete/rewrite is no problem. PMMail might be doing
some sort of polling, waiting for your script to finish.

While it sounds silly, it's a good solution in some cases. I do the same
thing in some scripts to do subject rewriting. However, I rewrite only
the subject line retaining the original length. This is a lot faster than
rewriting the entire message body.

I'd have to see your code, but this really smells like a logic error of
some sort.

You might be able to use:

'copy nul' fileName

This will empty the file and I may not delete it first.

I can't see any reason to not keep this on the list. This way others can
learn too.
