SMTP Fehler: [451] 4.7.1 Service unavailable - try again later

  • Hello,

    since yesterday I have this problem, when amavis-plugin is active. If I deactivate the plugin, everything works fine.

    I haven't changed anything, before it happen.

    1. WARNING: No clamd server appears to be available
    2. ERROR: Failed to initiate streaming/fdpassing

    Have someone the same error?

    Can someone help me?

    I have the latest i-mscp on debian.
