Your Exim is fine, had that last week with a 4.94 . It was caused by ANTIVIRUS (Avast if i'm not mistaken) Software intercepting the transmission, presenting a bogus cert and than the client rejected it and that was it for the connection. It did not leave a trace in the logs. @Devs: Maybe a nice FR to put a "421 client aborted connection from ip x.x.x.x." in the logs. best regards, Marius -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
