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/ma...ter-38.html;_ylt=AjfM2CC6HeSBKZ8ccwmpkWMIJHdG ) - how would I limit that in postfix? I'm guessing its somewhere in the main.cf or master.cf files. Thanks in advance!
