PERM_FAILURE: Gmail tried to deliver your message, but it was rejected by the recipient domain. The error that the other server returned was:

554 TRANSACTION FAILED.
This is apparently a natural result of the perceived BlogSpot spam blog problem. My suspicion is that AOL will suffer more than Google, by doing this. Blogger blog owners may be caught in the middle, unfortunately.
If your blog readership focuses upon AOL customers, you may do well to consider publishing your blog externally. Your BlogSpot URL won't go away - you'll just get a new, non-BlogSpot alias, that you can publicise in email. As in email, to AOL customers.
If you're an AOL customer, get a GMail account. GMail is free, and you should be able to have it extract your AOL email automatically, so you don't have to use the AOL interface.
