If this is indeed a connection closed after message delivery, there are a few possibilities.1. ESMTP PIPELINING was not used to pipeline "DOT" and "QUIT", the server sends QUIT separately, but does not wait for a response and hangs up.
Of interest, Exim as client has not (up until now) done $subject. It is quite happy with it being done, as a server. I do find, when implementing it, that both Outlook and Google screw up, as server, when Exim does it. In both cases, CHUNKING had also been used. I wonder if anyone else has observed this? I see no theoretical bar to pipelining QUIT after BDAT LAST, but if servers out there are are commonly broken I may need to restrict the implementation. Either non-Chunking only, or a hostlist option on the transport, come to mind. -- Cheers, Jeremy -- ## 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/
