This may not work but adjusting the configuration variable SMTP_MAX_RCPTS in mm_cfg to a lower figure, assuming you have not already over-ridden the default value of 500 in Defaults.py, might get you below whatever limit is being set for delivery to a single mail domain in a single SMTP transaction, if that is the rule that is being applied and causing your problem. But this might not work if they are checking for a common hash value for message bodies across multiple deliveries. In that case using personalization of messages under MM 2.1.x might get you over that hurdle but at the expense of a performance hit for your mail servers, with a significantly larger volume of SMTP transactions, which might trip another rule ... > One obvious way to circumvent the problem is to manually split the > list into > parts > and create, a list of lists.
