Hola Amigos una Ayudita...
Instale sobre Debian 6 postfix + dovecot + Squirrelmail y trabaja bien.
El problema que tengo es a la hora de añadirle seguridad al servidor y a los correos, al instalar MailScanner y Clamav, los correos ya no me llegan, se quedan encolados en HOLD
en el mail.log

se queda así enviando ese mensaje indefinida mente en un bucle sin fin, he probado muchas cosas y al final ya no se que más hacer se me han acabado las ideas.
PDT: si desinstalo MailScanner y Clamav el servidor vuelve a funcionar correctamente
Gracias de antemano..
