The maximum number of recipients that can be specified for a single message is 300. Users receive the error "452 Too many recipients" when they attempt to go over this limit.
By default the MailEnable server imposes a limit of up to 300 recipients to a single message. This is to help reduce the amount of spam sent if anyone does guess a users password. This value can be altered in the administration program under the SMTP Security options.
