Lo instalé dovecot dovecoot-mysql postfix and postfix-mysqldesde debian repository 7.
Los empiezo con /etc/init.d/postfix starty/etc/init.d/dovecot start
pero cuando lo uso nmap localhostveo el siguiente resultado: root@sito:/etc/dovecot# nmap localhost
Starting Nmap 6.00 ( http://nmap.org ) at 2013-09-12 07:35 IRDT
Nmap scan report for localhost (127.0.0.1)

Pero cuando lo uso netstat -nap |egrep -i dovecotveo el siguiente resultado:

Mi preguntaes, ¿dónde está dovecot? No veo su' ports....
Respuesta1
En cierto modo respondiste tu propia pregunta al incluir esa salida de netstat; Las líneas que comienzan con "unix" son sockets Unix, no sockets (puertos) tcp.
Como se sugirió, debe configurar Dovecot antes de que realmente se inicie y funcione.
