Autor: Ian Zimmerman Fecha: A: exim-users Asunto: [exim] Temporary reject when random sender verification should
succeed
I just turned on callout sender verify with the random option.
Strangely, the first (and only the first) connect from many domains
after that is temporarily rejected, although the callout seems to
succeed with a 250 status code. The log lines look like this:
2018-05-29 12:25:26 acl_check_connect: connect from 23.253.242.70

I obfuscated my mx hostname and my domain name, and only these two
items.
Why exim "Could not complete" the callout when it got a success code?
Again, this only happened for the first time for each domain after the
configuration change. Subsequent connections work normally and log
nothing about the callout.
