Liebe(r) $MAILBOX
Deine Mailbox nutzt im Moment $MBOXSPACE b ($MBOXPERCENT %) auf dem Mailserver. Wir wuerden dich gerne erinnern
dass deine Mailbox nur $HARDQUOTA b beinhalten darf.
Um Probleme zu vermeiden, entfernen Sie bitte Mails in Ihrem Posteingang, Gesendeten Objekten und allen Unterordnern
Liebe Gruesse,
