I want to limit recipient per message. I search on website and find some usefull information. Follow them, I configure in my main.cf
smtpd_recipient_limit = 3
smtpd_recipient_overshoot_limit = 1
After that, I send a test mail to 4 recipients from my local domain mail. This functions works, the server don't permit to send.
But when i send a test mail to 4 recipients from external domain mail (gmail). It doesn't works. My server permit to receive . It seem this message broken up into smaller lists. And pass my rule.
How I can limit recipient per message from outside domain mail ?
Pls help me
