Problem with account to logon at mail and support

Problem with account to logon at mail and support

Hello:

This morning, I began to have problems opening my email account:   ilda@rskm.com.mx

I put my USERNAME (email) and my PASSWORD, the mail tries to open, and suddenly it closes and ask me my  username and password.

Then, I tried to put a post in this fórum, with that account, and I can't.  The sesión is closed suddenly

We have another account that began with problems:   Fernando@rskm.com.mx

Can you help us?
