Issue Cannot access Mailbox....

[Mihail Llaftiu]

Hello, i would like to ask why i can't login to my mailbox. Since couple of days we transfered from papaki.gr to hetzner.de hosting company. We rent an VPS with plesk, and by all default settings on it. We moved couple of client's accounts and every account can't login to its' mailbox. We created mail accounts as [email protected] (where example is their domains), we can have access at webmail.example.com by using roundcube as webmail software. But everytime we put their data correct - incorrect the reply is that "
The connection to the storage server failed." (this error message is by translation, hope it helps). So please can you help me find a solution of it? Looking forward for your answer, kind regards!
