EAS/autodiscover on shared host

boohoomoo

Hi,

So my mailcow server is sharing the host with a couple of other services that all sit behind a pfSense firewall and haproxy.

I hava opened up the imap ports and my email clients are able to connect to mailcow no problem. I have also set up an FQDN for webmail (webmail.example.com) via which I can reach mailcow.

But I am having issues getting EAS/autodiscover to work. Unfortunately, this is an area I have no expertise in at all.

My DNS entries contain “CNAME autodiscover webmail.example.com” and “SRV autodiscover.tcp.example.com”. But it does not work and I have no clue why.

Would someone please be able to tell me either that those entries are correct or what CNAME and SRV entries I need to have to direct EAS/autodiscover to mailcow?

Many thanks!

boohoomoo What error(s) do you get? Do any get logged in the Autodiscover section of the logs in the UI? The SRV should be _autodiscover._tcp (note the underscores)

Okay, frist of all:
The SRV entry is as faisal described. I was writing from memory and forgot the underscores. But they are there. So I take it, the DNS entries are alright.

Now, as for errors:
When I have Outlook (from Office365) try to autodiscover (using the old set up dialog as per this guide: https://mailcow.github.io/mailcow-dockerized-docs/client/client-outlook/), it ends up with an IMAP config. So, no errors in Outlook.

In Mailcow in the autodiscover protocol I find two lines:
17.03.2022, 18:28:46 Microsoft Office/16.0 (Windows NT 6.2; MAPICPL 16.0.14931; Pro) test@example.com 192.168.5.7 IMAP, SMTP, Cal-/CardDAV
17.03.2022, 18:28:38 Microsoft Office/16.0 (Windows NT 6.2; MAPICPL 16.0.14931; Pro) none xxx.xxx.xxx.xxx Error: must be authenticated

So this is the only error I get. But I don’t know what it means (in particular, what I need to do differently).

Many thanks!

Any ideas?
