I've used a few free email tools for a while but e4ward seems to be
the hardiest of the lot.  One of the things I liked about one of the
other (now defunct) services was the ability to create a new forward w/
out needing to log in.

Something like sending an email to
target.recipient.at.targetURL....@jmvdw.e4ward.com would verify the
SMTP source (for "security"/validation) and go ahead and automatically
create a target.recipi...@targetURL.com -> JM...@e4ward.com forward.

With the SMTP validation no expiration or extra characters seemed
necessary and no login was needed.

Is there a way to do this with e4ward?

Thanks!
