Quota - Invalid bytes limit

Hi

Just for if it's helpful for anyone, I have solved the issue modifying 
the quota-warning script. I realized about this log line:

Apr  8 09:34:24 server dovecot: lda(user at domain.es): Debug: Ignoring 
overridden (-o) userdb setting: plugin/quota_rule

So I changed at the script this line

#cat << EOF | /usr/libexec/dovecot/dovecot-lda -d $USER -o 
"plugin/quota_rule=*:bytes=%$"

whit this one:

cat << EOF | /usr/libexec/dovecot/dovecot-lda -d $USER

And now it's working fine.

Best regards
