Can't register on Nginx forum or mailing list!

[maxmilhas.openid.org.cn]

I have tried to register in Nginx forum, but I didn't receive the email message to confirm and activate my account. I have checked spam folder too, no message. The same problem is happening with the Nginx mailing list. I tried to subscribe to it, but I don't receive any message to confirm my registration.

Both tries have about 48 hours now.

I can register to other forums and mailing lists normally. I even tried this to be sure my mail server and accopunt is properly working.
