Cannot receive emails on accounts with aliases associated to them.

Hello,

I'm unable to receive emails on accounts with aliases associated. Sending to the alias does nothing too. It used to work, but it stopped at some point (don't know when).

What's even worse, is that the email is not being reported as not delivered, so whoever is emailing me, thinks I got the e-mails. They just end up in a black hole.

Is this a known issue? Can it be solved and be sure that it won't happen again?

Thank you.
