Newbie ? with $ reward - Postfix: Limit the # of messages sent per SMTP Connections

[lead97]

Hello everyone - this is my first board message. I hate to ask for help but i'm new to Postfix and I'm trying to solve an issue with mail delivery. I appreciate everyone's time and if someone helps me solve this issue i'll send them a token paypal $5 payment - I know its nothing much but it is a show of my appreciation.

This should be a simple solution for a Postfix admin. I want to limit the number of messages that I send per SMTP connection because some of the larger mail providers (Yahoo) recommend that I send a MAX of 20 emails per SMTP connection ( http://help.yahoo.com/l/us/yahoo/mai...8ccwmpkWMIJHdG ) - how would I limit that in postfix?

I'm guessing its somewhere in the main.cf or master.cf files.

Thanks in advance!

The only way you can do that with postfix is to use a policy daemon. a good one is http://www.policyd.org/ here is the documentation to setup the limits.

I set the smtp_destination_recipient_limit to 20 and I hope that will limit the number of emails delivered per SMTP connection to 20 - if anyone has any thoughts i'm all ears!
