    Hi; my private mail server has been receiving a lot - running into the
    thousands - of access attempts from 177.223.136.xxx over the past week
    or so, which appears to be a Brazilian outfit. Before I firewalled the
    stuff, I saw the mail was always from assorted domains containing the
    string 'mailtrack' or 'trackmail', none of which existed, so it was
    never going to be let through.

    They're firewalled out now, but nevertheless filling the firewall logs
    which is a pain. They seem to start and stop a bit, but the overall
    quantity seems to be increasing.

    Anyone else seen this?

    Nope (two VM's on a French subnet, 1 VM on a US subnet).
