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, subscriptions=yes location=maildir:~/Maildir 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:
