Hi all, Thanks for your replies and the interesting comments. Greetings, Simon -----Ursprüngliche Nachricht----- Von: Billy Irwin via Blind-sysadmins Gesendet: Montag, 26.

If you follow best practices and build a good reputation, you will not have any issues. Delivering to Yahoo based servers are probably the worlds worst. It took some tweaking to figure out a method for reliably delivering high volumes of mail to them correctly using Mailman for example. I do offer a service to customers whereby they can use one of my mail servers as a relay with no issues. You just have to ensure you don't allow Spam to get through. Return Path is one good source to review best practices. If you have the drive and ambition you can certainly get it done. There is a trend that a lot of I.T. shops will opt to move things off premises and defer to SaaS. As the one who gets final say in my day job, I will not be doing this. In fact, I have brought back our Exchange environment because of the way Microsoft nickels and dimes you. The industry needs to seriously reconsider what and how things get moved to the ever expensive cloud. I do recommend off site backup solutions. Most importantly, I do everything we possibly can to keep services in house. You just never know when you are going to want your data back in your hands. At the end of the day, you have to do what makes sense for your organization. Very Kind Regards, Billy -----Original Message----- From: Jason J.G.
