postfix problem

#1
Hi Leute,

ich habe ein Problem und komme nicht dahinter!

ich habe einen Debian GNU/Linux 7.3 (wheezy) Server mit
dovecot, postfix, mailscanner, amavis ,.. am laufen!

postfix version = 2.9.6

Wenn dieser Mailserver eine Mail von extern mit ca. 100 oder mehr recipients (alle recipients werden auf diesem Server gehostet) erhält, bricht dieser den Empfang ab!

Hier das log von dem Sendeserver:

und dann ist einfach aus!

Leider habe ich kein aussagekräftiges Log da ich verbose Login erst danach eingeschalten habe!
