Email Portability Approved by Knesset Committee

There are huge differences in LNP/WLNP vs. Email Address portability.

Prior to LNP/WLNP, there was already SS7 which is, essentially a centralized
layer of indirection for phone numbers. This was necessary in order to support
multiple LECs serving the same NPA-NXX anyway.  Once that was in place,
LNP/WLNP was almost a no-brainer from a call routing perspective. The
issue was with the administrative process and the level of ethics exhibited
by some of the phone-company participants (slamming, etc.).  We saw the
same thing in DNS.  LNP is much more like domain name portability
than email address portability.  We already have domain name portability
and had it long before LNP/WLNP.

The owner of a domain has always been able to change the NS records
pointing to the authoritative DNS servers for said domain.

If users care about email portability, they should simply get their own
domain and move the domain around as they see fit.  Given google
and other email hosting providers which will trivially host your email
domain and the low annual cost of registering a domain, I'm not sure
why legislators would think doing it differently is a good idea.  If I were
an Israeli ISP and this law were to pass, I'd simply discontinue providing
email service for my customers and suggest they get their email via
Google, Yahoo, or other free email service.
