Maybe what appears to be a block is actually some sort of problem with part of their distribution system. My guess is that, just like the Postal Service, they have regional e-mail servers or access nodes. Wilson- This is true and we also need to consider the fact that AOL is in the process or refining its spam filtering systems and possibly that could be changing on a regional basis as well. There are definitely too many instances of non-receipt for it to simply be a matter of how an individual has their personal spam filters set. Joan
