How do you achieve maximum device/app compatibility with autodiscover/autoconfig?
Question asked by Adam - 7/3/2020 at 10:15 PM
I've been struggling to achieve a standard setup where SM and the DNS provide all the correct responses to all devices across different OS (Windows, Mac, Linux, iOS, Android) and different apps (MS Outlook, eM client, Windows Mail, K9 Mail, Outlook for Android/iOS, Apple Mail, Android/Samsung Mail).

Is anyone able to share their ideas or what's currently working well for your install?

Yes, I've followed the KB article on SM site, but its just not achieving it well across the range of devices and apps - im sure there's more to it than written there. For example there's a web.config redirect or autodiscover.xml on that KB article but no .htaccess - so the article seems incomplete to deal with multiple platforms of webhosting to serve .htaccess also.

Thanks in advance for your recommendations!

Autoconfig, if I'm not wrong, is only used by thunderbird or at least mostly. It has a different format than Autodiscover and SmarterMail has no support for it AFAIK.

For autodiscover we had some good success with DNS entries like this for every concerned domain:

 autodiscover           IN     CNAME

 _autodiscover._tcp   SRV 0 0 443
 _submission._tcp     SRV 0 1 587
 _imap._tcp           SRV 2 1 143
 _imaps._tcp          SRV 1 1 993
 _pop3._tcp           SRV 4 1 110
 _pop3s._tcp          SRV 3 1 995
