    Since I configured mail service on ISPconfig every time tath I send a mail to a 1and1 server I receive a returning email with error like this:
    063A525221 2043 Tue Sep 6 09:51:06 [email protected]
    (host mx01.1and1.es[XXX.XX.XXX.XX] refused to talk to me: 554-kundenserver.de (mxeue102) Nemesis ESMTP Service not available 554-No SMTP service 554 invalid DNS PTR resource record, IP=XX.XX.XX.XXX)
    [email protected]

    Anyone has the same error? Does anyone know how to solve?

    Sounds like you need to correct your PTR record in DNS.
