You need them for all.
Why? Let's say that the one of the virtual domains is "example.com". When
someone sends an E-mail from "[EMAIL PROTECTED]", SPF doesn't know or care
about the taisweb.net domain -- it just knows that the E-mail is claiming to
be from example.com, so the example.com SPF record is checked.
In other words, SPF doesn't know or care whether your domain is a virtual
domain or IP-ful domain.
