This sounds somewhat similar to my experience. The main issue here is, if I interpret this correctly, that your outbound mail volume is below their threshold for caring at all. If you're below whatever the limit is (in the thousands per day at least, but I forget the specifics), and you are not their paying customer, they will not be moved to adjust their system at all. And as indicated in a thread here not too many weeks ago, there are indicators that the system they use is something that was created by people who are no longer around, hard to maintain and opaque to the people tasked with the care and feeding. Somebody who contacted me as a result of that thread from somewhere that seems to be close to the processes told me that "if you feed the same message to the system twice, you will get different results" or words to that effect. The method I have used with some degree of success is to 1) send your mail from your regular address 2) contact the recipient via a gmail account and tell them to check their Spam folder, if your message is in there, report as not spam Repeat enough times and it might help if your setup is in reasonable shape otherwise. This of course does not help in those cases where their system chooses to just make your message disappear after reporting message received back in the SMTP dialogue. I have published some rants on this earlier, findable via the list archives. All the best, Peter -- Peter N. M.
