    ISPConfig sets a expire time of 7 days. MXToolbox suggests to use a value of 1 - 2 weeks, which I wont use on my servers. It is up to you which value you set, you can configure it in the zone settings. the value is always in seconds.

    Regarding Serial number format, which exact serial number do they complain on?
