Any idea for the REJECT 4 to reject the header "From: us e...@domain.tld

The example I showed you, while being much more readable, already included
the space.
Dare I suggest that the whole exercise is likely rather pointless. There
are surely better ways to deflect spam than attempting to use regexps
for RFC-enforcement on the From: header.
This likely yields very little net benefit, and is rather fragile. The
OP is IMHO better off directing his energies elsewhere...
I don't disagree.
I was ready to drop it after my suggestion to use more readable and less
error-prone character classes fell on deaf ears.
But he hasn't rightly stated why he wants to do this, so I didn't want
to flat-out say he shouldn't.
