lda: Unknown mail storage driver maildir

hi all,

I have a successful (self-compiled from source code) Dovecot v2.2.16 setup
active on my Solaris-10 server, with mails stored in user's $HOME/Maildir

The mails are fetched from the ISP with "fetchmail", using a
"cron" job

fetchmail -f $HOME/etc/pop3.myisp

where the file "$HOME/etc/pop3.myisp" contains

set logfile fetchmail.log
poll pop.myisp.be with proto POP3
user myIspmailLogin there with password myIspPwd is rob here nokeep
mda "/programs-3.2/amd64/64/libexec/dovecot/deliver"

Now I want to get it also running on a Debian server, with the same Dovecot
version, and exactly the same config files, but here I get the following
messages in "/var/log/mail.log" when launching a "fetchmail"
attempt :

Mar 17 14:36:20 apps_b dovecot: lda(rob): Debug: Effective uid=1000,
gid=1000, home=/home/rob
Mar 17 14:36:20 apps_b dovecot: lda(rob): Debug: Namespace inbox:
type=private, prefix=, sep=, inbox=no, hidden=no, list=yes,

Mar 17 14:36:20 apps_b dovecot: lda(rob): Error: User initialization
failed: Namespace '': Unknown mail storage driver maildir
Mar 17 14:36:20 apps_b dovecot: lda(rob): Fatal: Invalid user settings.
Refer to server log for more information.

So it seems to be complaining about "maildir" storage driver ?!

My config is:

# /programs/3.4/x86_64/64/sbin/dovecot -n -c
/usr/local/dovecot/dovecot.conf
# 2.2.16: /usr/local/dovecot/dovecot.conf
# OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.4
disable_plaintext_auth = no
first_valid_gid = 1000
first_valid_uid = 1000
last_valid_gid = 1500
last_valid_uid = 2000
mail_debug = yes
mail_location = maildir:~/Maildir
namespace inbox {
? location ? mailbox Drafts {
??? special_use = \Drafts
? }
? mailbox Junk {
??? special_use = \Junk
? }
? mailbox Sent {
??? special_use = \Sent
? }
? mailbox "Sent Messages" {
??? special_use = \Sent
? }
? mailbox Trash {
??? special_use = \Trash
? }
? prefix }
passdb {
? args = *
? driver = pam
}
postmaster_address = rob at mydomain.be
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
? driver = passwd
}

   Why did you self-compile several years old dovecot ? Please use 2.2.36 or
2.3.5 instead...
