Yahoo does not require an existing address.
Hotmail/MSN/Live does not require an existing address.
AOL/AIM does not require an existing address.
Gmail does not require an existing address. [1][2] does not require an existing address.
It seems *does* require an existing address.  This appears to be
the exception rather than the rule.

*If* Gmail were to require an existing address, prohibiting Yahoo
addresses *might* make sense.

[1] This seems to depend on the IP address used to sign up for the
google account. When signing up through a TOR exit node (at least at the
time that I tried it, which was > 1yr ago) Gmail asked for either a
cellphone number for text confirmation, or an existing email address.
Yahoo did not differentiate between TOR exit nodes and non-TOR IPs.

[2] Google apps accounts however do seem to require a preexisting email
address, however gmail addresses are accepted for that purpose.
