Hello Olivier,
About your configuration, I don't understand why you use
"mail_privileged_group = vmail" because it's only for mailbox not for
MaildirThey say "Currently this is used only with INBOX when either its
initial creation or dotlocking fails."
Then the only difference I have is that I don't have this specific line that
overrides the global settingsargs = uid=vmail gid=vmail home=/var/vmail/%d/%n
Also I notice after a reboot that I have the initial problem even if I start
dovecot from command line. Before writing the first email I had touched the
ulimit
You told me that dovecot runs with the _dovecot user, ok. Still I don't
understand why the dovecot section in the login.conf is not taken into account
after the command[ -f /etc/login.conf.db ] && cap_mkdb /etc/login.confI think
this is the source of my problem
Here's my dovecot config, nothing special I think
# dovecot -n
# 2.2.21 (5345f22): /etc/dovecot/dovecot.conf
# OS: OpenBSD 5.9 amd64Â ffs

Hello Mik J.
in first, sorry for my bad english.
Did you mix sysuser and user required to read the dedicated mount point for
virtual users (virtual mailboxes storage) ?
OpenBSD team provided the sysuser _dovecot to run the daemon.
I use on my side specific user also to read the Maildir folder in a specific
mount point : /var/vmail with user vmail
(vmail created manually : vmail:*:xxxx:xxxx:Virtual
Mail:/var/vmail:/sbin/nologin)
Only the user vmail writes on the dedicated mount point for all virtual
mailboxes.
Dovecot is running with _dovecot sys account.
May i suggest you to read in parallel : http://wiki.dovecot.org/HowTo
Mainly the section userdb configuration, where you declare the user required
to read & write the virtuals mailboxes stored.
In my case i mixed sql authentication with static userdb part.
my dovecot -n :
# 2.2.21 (5345f22): /etc/dovecot/dovecot.conf
# OS: OpenBSD 5.9 amd64Â ffs
first_valid_uid = 1000
listen = *
mail_gid = vmail
mail_location = maildir:/var/vmail/%d/%n/Maildir
mail_privileged_group = vmail
mail_uid = vmail
(...)
passdb {
 args = /etc/dovecot/dovecot-sql.conf.ext
 driver = sql
}
(...)
userdb {
 args = uid=vmail gid=vmail home=/var/vmail/%d/%n
 driver = static
}
