Topic: Best Open Source Mail Server Around
I just wanted to leave a post about my company's experience with iRedMail. This has been an invaluable tool for our business and the company worked with us to renew our license after I inadvertantly let it expire. We are looking forward to working with this company for years to come and honestly is one of the better email solutions out there. We moved from Kerio which had terrible customer support and we have never regretted our decision.
