Dear Javier Ortiz,
Thank you for your request.
We have located and fixed your issue:
There are 2 servers:
22.214.171.124 (mail.funmanga.com) - mail / cpanel/mysql server 126.96.36.199 (funmanga.com/aplimovil.com) - private java server
There was misconfiguration in DNS zone. We have changed it so that mail will be delivered to mail.aplimovil.com (which was changed to 188.8.131.52).
DNS will be updated within 4 hours.
Ftp issue may be connected with issue. Ftp accounts you are managing within CPanel work only for CPanel server. In order to manage ftp on private java server please contact us.
Looking forward to hearing from you.
