    Hi all,
    I just noticed the DKIM key strength parameter on ISPConfig dashboard.
    It's set at lowest value (1024) by default.
    Is there any reason not to set it to 2048 or 4096 ?
    Thanks in advance !

    you can change the strength by yourself. keys with a strength > 1024 can lead to dns-records with > 255 chars and some dns-hosters do not allow such (long) records.

    Thanks (once more) @florian030 for your answer.
    (just tried 2048 on some DNS records, hopping it will suit)
