https://www.howtoforge.com/communit...nfig-autodiscover-for-simple-platforms.59666/ I was quite surprised that auto discovery isn't part of the current out of box build, am I missing something. It seems to me that I'll have to modify the default dns template too, and I'm not sure how to implement the suggestion above so it sticks.
There is also this: https://blog.schaal-24.de/ispconfig/autoconfig-und-autodiscover-mit-ispconfig-automail/
just to note, Microsoft have changed something in recent versions of outlook, so that automatic setup does not work with new versions when using Florian's scripts that Taleman links to. Florian hasn't had the free time to troubleshoot and update. older versions of outlook still automatically configure themselves ok, as does thunderbird. I've not looked into the method the first post links to, I would assume it was affected the same way, and if so, have no idea if it's been updated/fixed.
Reading the Readme of Automail, I discovered there is also English documentation: https://schaal-it.com/ispconfig-automail/ The link in #2 is the German version.
