I’ve found it to be reasonable as part of getting users set up: my users generally follow a guide that we give them — “set your smtp server to this, set the port to 465, click on SSL”. They already have to ask what the hostname is for setting up their account. (I don’t understand why Apple doesn't use SRV records — when you enter an email address, they make an HTTPS connection to their servers with the domain to see if they can auto-setup the results for the user, but there’s no clear way to get into their system. I suppose SRV records open up some DNS MITM attacks during initial setup? I don’t get it.) Getting existing users to change settings is, of course, entirely different. -Jeff ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
