[Gutl-l] Squirrelmail, dovecot, postfix y TLS/SSL.

[Rommel Rodriguez Toirac]

Saludos Lista;
Por acá estoy intentando hacer algo que se trató en la lista hace un tiempo 
pero que no dieron solución. 
 La configuración de mi sistema de correo es con Postfix+SASL+TLS y dovecot+SSL/
TLS
 Funciona para Outlook, Thunderbird y Kmail.
 Desde el squirrelmail logro abrir la sesión del usuario y veo la lista de 
correo, pero a la hora de enviar correo no logro hacerlo.
 Las trazas me dicen esto:
