Como en la naturaleza, la guerra entre el spam y los antispam, evolucionan. Cada mecanismo de ataque genera uno de defensa y viceversa... al grano. El otro dia vi que MailScanner viene con una config por defecto para analizar todos los correo que no sean superiores a 200k...
# Spammers do not have the power to send out huge messages to everyone as
# it costs them too much (more smaller messages makes more profit than less
# very large messages). So if a message is bigger than a certain size, it
# is highly unlikely to be spam. Limiting this saves a lot of time checking
# huge messages.
# Disable this option by setting it to a huge value.
# This is measured in bytes.
# This can also be the filename of a ruleset.
Max Spam Check Size = 200k
Esta justificación, en mi opinión totalmente valida, pero es muy sutil. El otro dia vi como se colaba un correo de 207k sin mostrar ninguna puntuación en mailscanner, simplemente decia "too large" :(. Para solventarlo aumentar ese valor.
