[Dovecot] dovecot security with IPv6

[Kārlis Repsons]

Hi Timo, hi all others!

In fact, I've only read one person claiming that IPv6 support opens up
"too many backdoors" [1], but anyway, as I intend to run just
particular services, please give me your opinion if it's insecure to
have a dovecot server, which is accessed through a public IPv6
address...
(or note just shortly what else could give a firm ground to such claims...)
