Hi, We were planning to setup iredmail server on a Linux machine. We have a domain. And we were planning to send emails with smtp using iredmail server. Before that i have some basic questions on it.Could anybody please clarify my below questions: 1) What all are to be setup/required before installing iredmail server on machine? 2) Can iredmail server be installed on cloud linux environment ? or a dedicated server is required? which one is better to maintain iredmail server? 3) My requirement is to send mails to bulk of users from the UI application. can it be possible with iredmail server? 4) When i sends a mail to specific user and the mail gets failed. delivery failed message should not go to user's mail address. it should be stored at my iredmail linux server. Is that possible? Thanks in advance?
