Hi Ivan, I receive such emails from time to time and I did not manage to understand the conditions when this happens. From a quick search it looked like it was related to the number of messages being received per certain time interval, but I could not confirm this based on the number of messages on our lists.
I also would be curios to know is someone solved this. пн, 23 дек. 2019 г. в 14:45, Ivan Pavlukhin <vololo...@gmail.com>: > Hi, > > From time to time I receive a following warning message (see quoted > below) from a program managing Ignite mailing lists.
