--- Comment #12 from Alex Presland <[email protected]> --- Monitoring now in place. All I need to do is get the user who uses the [email protected] to route their email back to that email address again (haven't seen the bug since 2016-02-08, after which they got fed up of losing emails and routed their email elsewhere). I think that the regular "421 ... Too many connections from same IP" response from Plus.net's mail servers is helping to expose this problem, by causing subsequent messages to be deferred. I've not done anything about this so far but once I've finished collecting data for this bug report, I'm going to use the serialize_hosts setting for plus.net MX servers to prevent this from occurring. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
