For some reason when i configure dovecot to act as the final LDA in procmail and set 
quota_full_tempfail = yes overquota mails get lost somewhere
As Virtualmin is relying for some of its functons on procmail droping it compleetly 
is impossible or at least very difficult.

I agree this is the solution for sending a warning email, but is there a method to actually 
prohibit users close to quota to send emails? 
Ie defining dovecot as authentication agent ?

to make things easier for everyone im posting snippets from my config of dovecot and procmail

:0wi
VIRTULAMIN=|/etc/webmin/virtual-server/lookup-domain.pl $LOGNAME
EXITCODE=0
:0
* ?/usr/bin/test "$VIRTUALMIN" != ""
{
INCLUDERC=/etc/webmin/virtual-server/procmail/$VIRTUALMIN
}
DEFAULT=$HOME/Maildir/
ORGMAIL=$HOME/Maildir/
DELIVER="/usr/lib/dovecot/deliver"
DROPPRIVS=yes

dovecot config snippets regarding LDA

protocol lda {
mail_plugins = quota
quota_full_tempfail = yes
}

for some reason this results in mails lost without any trace when users
are over quota (i would like to requeue those emails for later delivery)

Most probably its not directly dovecot related but as most people here
are more or less runing mail servers so maybe someone could help me
further.
