confMAX_RCPTS_PER_MESSAGE interaction with MS Exchange 2003

[grendelos]

Greetings,

I have a situation where I am using a Senmail server as an external relay and MS Exchange 2003 as an internal email server. I have put in a parameter of

define(`confMAX_RCPTS_PER_MESSAGE', `9')

The idea is to have unlimited recipients for internal email messages through Exchange, but to limit recipients on external email addresses.

The problem appears to be with Exchange as it relays through my Sendmail server. If I send through Exchange with 10 external recipients, Exchange automatically breaks up the message into 9 and 1 recipients. If I send through Exchange with 11 external recipients, Exchange automatically breaks up the message into 9 and 2 recipients.

I am not certain how to get around this problem. Any ideas?

After reading more about "define(`confMAX_RCPTS_PER_MESSAGE', `9')", I can see how this parameter may not be the best solution. Apparently when the recipient limit is exceeded, Sendmail tells the sender to try again later on the remainder of recipients, which Exchange dutifully does a few seconds later.

So, does anyone have an idea of how I can implement a policy of limiting external recipients?
