You misunderstand.  What is Gmail / Google specific about it is that this is
going on for nearly 5 years using the same recipient mailbox because it is
so far impossible to let Google know about it so that Google can can delete the
mailbox being used to receive the results of the relay testing which would
force the spammer create a new receiving mailbox nearly every time they test.

Similar probing using receiving mailboxes on other major email providers
systems does not last last more than a day or two before the mailboxes get
deleted after mail admins reported them.

Anyone who tries to do that will rapidly find out that it does not work and
they certainly won't have to wait 5 years to find it out.

There most certainly is something that Google can do.  They can cancel the
mailbox that is being used to receive the results of the relay testing,
provided it is possible to let Google know that the mailbox is being abused
that is.  I just don't have that difficulty with other major email providers.

Mike reports in another reply that he has unearthed a possible mechanism to
let Google know what is happening so maybe the problem has is becoming soluble
now.  It will be interesting to see if the mechanism he found works.
