Thanks for the observation. Just today I've noticed a lot of lines of
this type when sync with Android and ActiveSync (few minutes ago I sent
an email with some tests I made with Android without any problem). In
Debian the PREFORK line (PREFORK=3) was commented. So I added a line
with PREFORK=20. After that, so far I have not seen lines with "No child
available to handle incoming request!"

Perfect! Thank you for the confirmation!

Good. Thank you for the confirmation.

Interesting. With this I can say that I see some light at the end of the
tunnel :-) I also appreciate that you've taken the time to make a
Wireshark capture. It was something that today crossed my mind (I was
running out my choices).

I'll do a test configuring the access to SOGo with https and I'll let
you know the results. Have you had any problems in Outlook using
self-signed certificates?

Thank you very much for your time.

Best regards,
