Autodiscover with cpanelemaildiscovery.cpanel.net?

Hello,


While this defaults to the cpanelemaildiscovery.cpanel.net our documentation does indicate that you can create your own autodiscover hosts:

Microsoft also provides their own if you're using their services. There are also a few other threads that discuss AutoDiscovery/AutoConfig which might be helpful as well:

cPanel Autodiscover, Exchange+POP

Autodiscover setting breaking outlook autodisover for domains setup to remote exchange server

Thank you,

 

Hello,


When querying cpanelemaildiscovery.cpanel.net with your email client you should be able to obtain basic configuration instructions such as:

Code:

$ curl -d 'test@cpanel.net' https://cpanelemaildiscovery.cpanel.net/autodiscover/autodiscover.xml
<?xml version="1.0" encoding="utf-8"?>
<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">

            </Protocol>
        </Account>
    </Response>

This appears to be experiencing intermittent issues though as I found while testing. I've opened an internal case to have this addressed. I'll update here when I have more information

 

So what this does is send a GET request to the domain in the email address which *should* return your server's specific autoconfig details:

Code:

$ curl -d '<EMailAddress>lauren@mydomain.tech</EMailAddress>' https://cpanelemaildiscovery.cpanel.net/autodiscover/autodiscover.xml
<?xml version="1.0" encoding="utf-8"?>
<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">
    <Response xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a">
        <User>
            <DisplayName>lauren@mydomain.tech</DisplayName>
            <EMailAddress>lauren@mydomain.tech</EMailAddress>
        </User>
        <Account>
            <AccountType>email</AccountType>
            <Action>settings</Action>
            <Protocol>
                <Type>IMAP</Type>
                <Server>mail.mydomain.tech</Server>
                <Port>993</Port>
                <DomainRequired>off</DomainRequired>
                <SPA>off</SPA>
                <SSL>on</SSL>
                <AuthRequired>on</AuthRequired>
                <LoginName>lauren@mydomain.tech</LoginName>
            </Protocol>
            <Protocol>
                <Type>SMTP</Type>
                <Server>mail.mydomain.tech</Server>
                <Port>465</Port>
                <DomainRequired>off</DomainRequired>
                <SPA>off</SPA>
                <SSL>on</SSL>
                <AuthRequired>on</AuthRequired>
                <LoginName>lauren@mydomain.tech</LoginName>
            </Protocol>
        </Account>
    </Response>

When it fails to resolve your domain or get the expected response (i.e. it gets a 301) it will return data specific to the local setup so cpanel.net related information for a test account.

I have an internal systems ticket open for this and it is getting attention, I'm sorry for the inconvenience and nope, not just you, thank you for bringing to our attention!!


Thank you,

 

Here's what the request looks like when ran this earlier for an email address on my personal domain:

Code:

# grep -r autodiscover /etc/apache2/domlogs/ |grep "17/Apr/2018"
/etc/apache2/domlogs/proxy-subdomains-vhost.localhost:127.0.0.1 - - [17/Apr/2018:09:16:17 -0400] "GET /cgi-sys/autodiscover.cgi?email=lauren%40mydomain.tech HTTP/1.1" 200 1196 "-" "autodisc/2.000 (cPanel autodiscover/autoconfig server)"
/etc/apache2/domlogs/proxy-subdomains-vhost.localhost:208.74.120.173 - - [17/Apr/2018:09:16:17 -0400] "GET /cgi-sys/autodiscover.cgi?email=lauren%40mydomain.tech HTTP/1.1" 200 1196 "-" "autodisc/2.000 (cPanel autodiscover/autoconfig server)"
/etc/apache2/domlogs/proxy-subdomains-vhost.localhost:127.0.0.1 - - [17/Apr/2018:13:47:31 -0400] "GET /cgi-sys/autodiscover.cgi?email=lauren%40mydomain HTTP/1.1" 200 1196 "-" "autodisc/2.000 (cPanel autodiscover/autoconfig server)"
/etc/apache2/domlogs/proxy-subdomains-vhost.localhost:208.74.120.173 - - [17/Apr/2018:13:47:31 -0400] "GET /cgi-sys/autodiscover.cgi?email=lauren%40mydomain.tech HTTP/1.1" 200 1196 "-" "autodisc/2.000 (cPanel autodiscover/autoconfig server)"

So the issue with the autoconfig through cpanelemaildiscovery.cpanel.net is happening on our side not yours and while the issue is ongoing I wouldn't suggest testing using it but you can if you like using the same command I used. To set up Autoconfig/Autodiscovery on your own server our documentation here goes over the steps:
AutoConfig and Autodiscover - cPanel Knowledge Base - cPanel Documentation

 

HI

Enabling proxy subdomains is what I would assume created all the records an explanation of proxy subdomains can be found here: Proxy Subdomains Explanation - cPanel Knowledge Base - cPanel Documentation

The following forum posts also go over customizing the autodiscover.xml and may be helpful for you:
Autodiscover
Autodiscover domain / server name
Autodiscover dns records

In order to send back different information, you can customize this further utilizing an xml file. There are links to both Mozilla and Microsoft for more details on the format. I would highly recommend reviewing that information.

Though you didn't specifically mention Apple, I wanted to make note: Apple® email clients do not support AutoConfig or AutoDiscover for IMAP servers. To use AutoConfig and AutoDiscover with Apple products, you must meet one of the following requirements:

- Your service provider must register with Apple's AutoDiscover service.
- Your server must run Exchange rather than IMAP.
