So it looks like mailx is behaving as intended. Look at /etc/mail/mailx.rc
if t
# mailx-only defaults here
...
else
# mailtool-only defaults here
...
# have to allow ~ escapes even though not using tty
set escapeok
endif
The "set escapeok" line is what is causing you grief. Get rid of that, and
your problem will probably go away, though others may be introduced. As a
result, we may not be able to "fix" this without introducing compatibility
issues. However, this work-around does the trick for me: add the following
to your $HOME/.mailrc file:
if t
# input is a tty
set escapeok
else
unset escapeok
endif
