I have two problems here:
First issue:
When I type for example:
do not open webmail page, just shows:
Not Found
The requested URL /webmail was not found on this server.
Yes the A record for webmail is created. Any idea?
Second issue:
When I go to setup the account on Thunderbird connect to POP, with STARTTLS but on SMTP is not connecting no matter option I choose. I am using Let's encrypt. And I check on website:
www.sslshopper.com
and insert my domain.tld and shows everything ok with let's encrypt.
Any idea?
On CSF i have ports open: 25,110,993,995,587,465
