This morning I discovered this in the logwatch report for our external MX
backup host.

STARTTLS: write error=syscall error (-1), errno2, get_error=error:00000000:lib(0):func(0):reason(0), retry

    From what kind of logfile are those lines? That’s not Sendmail log style.

    The first system in question simply does not support TLS and it fails while testing.

    Without knowing your Sendmail setup and what is causing the kind of log content it is hard to give you a hint. Exit state 75 is TEMPFAIL. STARTTLS works for inet08.hamilton.harte-lyne.ca.

    I have to correct myself. This is MCI logging of Sendmail (Mail Connection Information (MCI) Caching Module).

    The log entries show dumping of MCI structure content.

    You seem to have communication issues between the systems involved.

    You better look into the /var/log/maillog directly to understand the whole information flow.

    Btw. CentOS 5.10 needs to be updated to 5.11 to be current with security and bug fixes.
