Tags address aliyun email email address etc html http list

The gray list, which is effectively blocking http://www.aliyun.com/zixun/aggregation/12915.html "> spam means, the principle is when a new email address sent over, will be rejected 2 times, and then the third time will receive. People who send spam generally, because the queue is too long, will not try to deliver.

The gray list will cause the first send delay, but after the second time there will be no problem. If you want to stop the grey list

Edit/etc/postfix-policyd.conf

# 1=on 0=off
Greylisting=0 #把1改成0

Restart the policy service

#/etc/init.d/postfix-policyd Restart
