i have set up an Webmin server and two domains attached.
I can send mails from Usermin also recive.
Now i want to connect to the imap server from my phone and thunderbird. and here every things go wrong.
I think it might be an DNS CloudFlare problem? I have made a A record pointing to ip
an MX mail pointing to ip also there is an MX domain pointing to domain. Can this be the issue?
Wich port should i use for in/out smtp - I have already assigned Lets encrypt to Postfix.
I really hope some one can help me with this stucked issue.
