Please explain the algorithm of delivery of messages:
sometimes they go in one direction for a few seconds, and
sometimes this time is from 5 to 10 minutes. Moreover, the
rapid exchange of messages (question-answer) does not work,
or there or back (quickly).
I want to understand the algorithm in order to communicate the
order of correspondence to their correspondents.
Opened new mailboxes and tested message delivery.
The result is encouraging: if the box is not overloaded with
messages, the delivery takes a few seconds, at least less than
I have mail on your domain provider - Yandex.
According to the results of the experiment, I recommend to keep
a separate mailbox for Delta Chat.
