Live IP address reload available in MailerQ 5.8

In version 5.8, we introduced the External MTA IPs functionality that enables users to set up NAT rules. These rules can be used to configure the MTA to send using public IP addresses of another server. Implementing this functionality required some under-the-hood changes in the way MailerQ loads and manages MTA IPs. A neat result following from this is that any new IP addresses that are made available on the server the MTA is running on, will instantly be available in the MTA for use as well. This means that if you’ve added new IP addresses to the server, you can assign them to messages, IP pools or IP warm-up schedules in a heartbeat without a restart!
