I don't follow - email.txt appears to be the content of each message.
What would be recreated if each message gets its own email.txt?

OK, so the issue (or my misunderstanding) is with only email.txt

That's exactly why I am concerned.  I'll have to find another TMPFS
solution, but aside from that, can you explain why email.txt has to
sit around with email content after amavis is done processing the
associated message?  Does this content stay indefinitely?
