I'm working at a small webhosting company. I have to set up the autoconfig (Thunderbird) and autodicover (Outlook) files, so that user (who have their own domain names, like www.userxyz.com) could set up their Email account in Outlook or Thunderbird by just providing their username and password.
I've followed this instruction (for Thunderbird). I've managed to build the .xml files, and everything works fine, but at the point (which I have linked to) where it says I have to set up a DNS CNAME record for every domain, I have a logic thinking problem.
We have many customers, everyone with another domain name. I can't set up a
autoconfig IN CNAME autoconfig.userXYZ.com CNAME Record for every customer we have. This would be not efficient. So my question is how could I handle that, or how would be that handled? I don't have a glue how I could ask that question in another way, but I hope someone understands it.
The user types in his Email adress (into Thunderbird), like
[email protected]. Thundbird is looking at
autoconfig.userXYZ.com/mail/config-1.1.xml if there is a config file. So I have to bring Thunderbird to look to another adress, like
autoconfig.hoster.com/mail/config-1.1.xml, so that I just have to manage one config file, and not thousands of them.
Sidenote: We are using BIND (9).
Thanks in advance. Regards, john.
