    Hi A client is complaining that some emails are not being delivered but no error message is being sent.

    I ran a check using MX Toolbox and got the following warnings:
    SMTP Reverse DNS Mismatch - Reverse DNS does not contain the hostname
    SMTP Banner Check Reverse - DNS does not match SMTP Banner
    SMTP TLS Warning - Does not support TLS.
    SMTP Transaction Time 15.169 seconds - Not good! on Transaction Time

    Do I need to start playing with the EXIM configuration or are these possibly false alarms?
