SMTP random ip address in sending email
Do you have any idea, on how to send email using smtp server that randomly change the ip address to prevent being block by other mail company like gmail, yahoo, etc.?
I have a php based mailer application and I used smtp accounts to send mail under CentOS 5 platform. My application is now in the point of sending thousands of mail per hour and the problem is, my server was easily block by other mail company, if my server will send consecutive mail for a short time.
Let say I need to send mail to "email@example.com,firstname.lastname@example.org and more", the gmail will consider my server as spammer and that way google will decide to block my server in sending mail.
I'm just wondering if there is any server configuration that will randomly provide ip address to send mail to other mail company.
I hope this make sense to you guys, thank you for any help.
