Hello,

thanks for your answer.

My mail client and exim are both running on my laptop, and the provided
logs are from that same laptop.

The fault is the delay between exim accepting the message, and actually
delivering it to the smarthost. During that delay, my mail client is
stuck too.

For example, here it is 4 minutes and 2 seconds:

> 2020-06-15 01:51:07 1jkcP5-000V8E-MS <= ...
> 2020-06-15 01:55:09 1jkcP5-000V8E-MS => ... 
> 2020-06-15 01:55:09 1jkcP5-000V8E-MS Completed

(full lines in the original bug report)

That delay is the exact time that my laptop had been put to sleep before
I did this test. I have made several tests, the delay is always the time
that the laptop has slept.

If I put my laptop to sleep longer, say usually a whole night, the delay
will be prohibitively long. In that case I have to kill the exim
process, which releases my mail client, then restart the exim service,
which delivers the stuck message and makes the problem disappear until I
put my laptop to sleep again.

Thanks,
