Our firewall blocks incoming mail if there are over 50 recipients in the cc
(carbon copy) field. One day, a customer sent us a mail with over 50
recipients, therefore the firewall blocked the mail. This customer reported
the situation to its contacts at work. As a result, we are instructed to
allow over 100 recipients in the cc field.

As I understand, the filtering policy is to prevent spamming, prevent mail
generated by worms, etc.

How do most companies handle this situation? How many recipients are
allowed in the cc field?

Any info are appreciated.

Regards,
