QUIT (QUIT)"This is irrelevant. All TCP services need to handle mid-stream client disconnect sensibly. QUIT is nice to send, but this is not always possible, so deviating from RFC 5321 by not sending QUIT is harmless.Apparently the content filter is waiting for QUIT *after* the connection is closed. Please file a bug report for the content filter.Wietse, this was a bug report for Postfix! Filing a bug report for the content filter because it does not check for a dropped connection is another story.And yet that's the real problem, the content filter must propagate not only QUIT but also EOF.
