Here is possibly a very stupid question - I have a client who has recently turned down a purchase offer for a domain name she actively uses. The person trying to buy the domain has informed her in a "friendly" way that her use of the email address of "firstname.lastname@example.org" is prohibited by ICANN. She now is greatly concerned and wants that address off her site.
I have never heard of such a restriction, and am only aware of requirements regarding postmaster and abuse addresses for a domain.
Is this the total BS I believe it to be, or am I missing something here?
Thanks in advance for any insight!
