DNS e-mail load balancing
My scenario is:
php-script(mail originating) -> DNS load balancer (vps server).--vps1(relayhost 1) |--vps2(relayhost 2) |--vps3(relayhost 3)
When I'm sending text mail (size ~8 KB) from a php script to a load balancer that is balancing the load of mails and delivering them to relay servers. I have relayed 40,000 mails for a mail campaign by using this.
But when I embedded an image in my mail (image size ~160 KB) the load balancer does not deliver any mail to clients.
Is this an issue of mail size or could it be another issue?
