This is not dovecot's fault. See here: http://serverfault.com/a/39561 In short: In Linux, binding to :: means "bind to both ipv6 and ipv4". Setting /proc/sys/net/ipv6/bindv6only to 1 changes this behaviour, and Debian had this by default in some testing versions of squeeze, as was recently discussed on the asterisk-users list: http://lists.digium.com/pipermail/asterisk-users/2013-March/278296.html
