How can I implement load balancing of transports. I have transports table with:
u...@domain smtp:mysmtpserver There are 2 smtp servers known as mysmtpserver. The questions are: - is DNS required to do such load balancing (i would rather not use DNS if possible) - if there are 2 "A" records for mysmtpserver, will postfix do round-robin transports or just cache one address for mysmtpserver and push all mail to it?
