    This has me baffled ...

    I am getting a timeout after DATA from a server. The other server gets a
    host disconnected after data, message may be sent more than once on their
    side. I get this in the log. Seems fishy to me ...

    Anybody go any ideas ?

    All the smtpd timeout parameters I know off are set as follows :
    smtp_connect_timeout = 0
    smtp_data_done_timeout = 600
    smtp_data_init_timeout = 120
    smtp_data_xfer_timeout = 180
    smtp_helo_timeout = 300
    smtp_mail_timeout = 300
    smtp_quit_timeout = 300
    smtp_rcpt_timeout = 300

    Response to client from the relay host:
