I'll use another server for sending e-mails soon, but can you please send a note to your mail service support about being unable to receive mail from "no-reply@deepbit.net" ? May be they will add it to whitelist faster.

Looks like Yahoo.com mailserver doesn't accepts mail from deepbit. I know about this and will do something soon.

Tonight the bitcoin instance for sending rewards crashed and started to show corrupted data. So I stopped sending rewards and will have to investigate it manually later today. I have precise logs about what happen, no coins are lost. I'm very sorry for troubles with delayed payouts.
