dovecotでエラー発生。

サーバー起動時にdovecotでエラーが発生して立ち上がらず。

エラー内容は以下のような物
Error: socket() failed: Address family not supported by protocol
Error: service(pop3-login): listen(::, 110) failed: Address family not supported by protocol
Error: socket() failed: Address family not supported by protocol
Error: service(pop3-login): listen(::, 995) failed: Address family not supported by protocol
Fatal: Failed to start listeners

対処法は以下の通り。dovecot.confでIPv4 だけをリッスンするように修正。

# /etc/dovecot/dovecot.conf (2.x)
#listen = *, ::
listen = *
