Topic: New users unable to connect to their mailbox

Hi,
I installed iRedMail and was able, from my machine, to access the mailbox of Postmaster, via browser (https) and via Thuderbird (IMAP 993) and read my emails.
However, after adding new users (via browser, /iredadmin), they were not able to connect, neither via browser (https), nor via Thunderbird (IMAP 993) to their mailbox.
There is no proxy involved and the entry of my mailserver is added to my local DNS.
The setup is intended for local use, not to receive/send to the outside. I tested successfully sending emails to postmaster.
What am I missing?
Thanks

Regards,

Re: New users unable to connect to their mailbox

Ok, got the webmail access to work when I added allow x.x.x.0/24; to etc/nginx/templates/roundcube.tmpl
Still got the Thunderbird thing.

Re: New users unable to connect to their mailbox

Thunderbird was able to connect too, it seems related to the self-signed certificate not being trusted, which is normal. But Thunderbird allowed me to add it as an exception.
All good then I guess, sorry for the trouble.

Re: New users unable to connect to their mailbox

Grab a free ssl cert from "Let's Encrypt" or other ssl vendors, don't use self-signed one in production.

Yep, will do, we have a domain wild cert that I'll be using.
Thx
