Glad to hear that it is working now. In case the error reappears, please bear in mind that the "18446744073709551615 B"
displayed in the config (Im assuming "doveconf" without switches) is the "empty" value, which actually means the value is "not
set" and the default_vsz_limit is used. http://wiki2.dovecot.org/Services#Service_limits
