I recently moved an ISPCFG3 installation to a new server so after configuring everything as desired, I copied over /var/vmail then changed my DNS to point to he new server and apparently everyone using POP3 had old email download again. The log files said: Expunged message reappeared, giving a new UID Now I still have a few email accounts to move and would like to avoid this, any idea what I could do differently or pay attention to?
