I received several emails from you as expected, but now I received a couple of empty emails. Something strange... see attached image
I don't know if this could be debugged somehow.
Both you and Earlz have gotten this once, but I am unable to reproduce this problem myself so far. I tried rebooting my testnet and I didnt get the three blank emails.
I am under the assumption everything else with email is working: we are not receiving dupes, we can send to all, we can send non encrypted and encrypted, and we can CC and BCC and send to multiple primary RCPTs now.
Lets keep testing emails otherwise, and confirm they are solid in all other ways. Possibly it will happen to me over the next few days and then I can try to catch it.
