I have postfix installed on a Centos server with 1 main ip 18.104.22.168 and a range of ips 22.214.171.124/24
The problem is : i can only send mail with the main ip 126.96.36.199, when i change it to another one from the range ex : 188.8.131.52 the mail stays in the queue ( status=deffered )
maillog error: to=, relay=none, delay=70314, delays=70164/0.01/150/0, dsn=4.4.1, status=deferred (connect to mx2.hotmail.com[184.108.40.206]:25: Connection timed out).
Additionnal infos : - No DNS setup yet - The block 220.127.116.11/24 is added by creating a new file in /etc/sysconfig/network-scripts called ifcfg-eth0-range0 and we've put all the ip adresses in it starting from 18.104.22.168 to 22.214.171.124 - I use to change the sending ip using "inet_interface = ip" on the /etc/postfix/main.cf
Could you please help me to fix the problem.
