  • In Pakets from private network to public network

    Happens here too, although rare:
    you can correlate the ip’s in the tcpdump against your postfix and netfilter logs in the mailcow admin ui.
    first occurrence was refusal of a mail delivery by dns blacklist,
    second one was a timeout after auth.
    Please post your results.
    Thx,
