I can just guess that you entered "mail.example.com" as the host name,
where "mail" would have been the correct answer. See the Question "The
hostname is a single word...".  If I remember correctly, the installer
asks for your domain later in the process.

I generally find it a bad idea to choose a host name "mail" since the
service might migrate away later and/or other services may be provided
by this host, but that's a matter of personal style.

I am, again generally, opposed to providing documentation that leads
the user click-by-click through a complex setup as your documents do,
but we have been through this a number of times and I don't seem to be
able to stop you.

Why do you install the X Window system on a mail server?

You spell out a lot of words in capitals, for example RELAY. This is
usually wrong, they are not acronyms.

Exim4 with dovecot supports maildir just fine, the "maildir not
available" message comes from an unrelated package that must be pulled
in by your way of installing. I surely have no libc-client on any of
my mail servers, and all of them are using maildir.

You can use swaks for debugging.

Please consider using Debian's adduser program to create system users,
and please consider having them generated with disabled login. Or,
even better, consider using mailbox storage ways that do not require a
system user.

Greetings
Marc
