Can anyone point me in the direction of a detailed how-to for setting up a
postfix and dovecot (proxy) node with dbmail?
In particular I'm looking for a how-to which shows dovecot authenticating
against the dbmail database directly.
The only example I've found is this one which requires a dupli
Hi Guys,
I was really hoping a couple of years later this would be addressed...
I'm running Dovecot 2.2.5 on FreeBSD.
Is there anyway to limit the number of auth attempts allowed in a
single session? The reason for this is because I have "fail2ban" setup

Well, first of all, why are you using mbox?
truncated output from my doeveconf -n
# for Local users
mail_location = maildir:~/Maildir
For SQL users
userdb {
args = /etc/dovecot/dovecot-sql.conf.ext
default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u
driver = sql
}
Ok, it seems i found the problem, i was missing the plugin declaration into
dovecot.conf
imapc_host = mail.foo.com
imapc_features = rfc822.size
pop3c_host = mail.foo.com
namespace {
separator = /
inbox = yes
}
protocol doveadm {
mail_plugins = $mail_plugins pop3_migration

I'm using dovecot 2.2.5.4 on debian6 squeeze.
