    the LOG File ever shows Network is unreachable, but the mails would be delivered.

    look at the IPs. The network unreachable is reported for IPV6. The actual delivery is done via IPV4. Looks like your sever has IPV6 enabled but no global address.

    Normal message,
    connect to[2a00:1450:4013:c01::1a]:25: Network is unreachable
    you also see :[]:25

    so you system if first trying the ipv6 ipnumber which is normal, ipv6 prefferes over ipv4.

    if you dont want these messages you have 2 options.
    or disable ipv6 for the system which i dont advice.
    or setup your system so it supports ipv6, which is adviced.

    more info (google) . ;-)
