Just before we go off topic 
I dont have many clients and as you know when you login to phpmyadmin on Virtualmin it is only bothered about the username and password so one central installation is fine. I prefer to login in with cleints details where possible to prevent me making an mistake but I only have one version of phpmyadmin.
Who’s to say that a single install can service many domains ? As I don’t use roundcube I’m not sure but i would think any login to the underlying mail server would work in the same way usermin works. If I can be bothered I will install roundcube and see if that works
I just tested.
Roundcube can retrieve emails from other domains in the same Server.
on www.abc.com/roundcube u can login with
info@abc.com and info@xyz.com
I think my problem is Thunderbird. My iPhone can retrieve and send emails but Thunderbird can only do so sporadically
Tx for testing. That would be worrying as most of my clients have an admin@domain.tld and sales@domain.tld and a few others.
As the mail server is working correctly, your mobile phone and roundcube can access the resource virtualmin has configured the mail server correctly, it may be worth asking your question on the thunderbird forum to see if anyone else is having the problem. Mind you as this is intermittent are you sure that fail2ban is not banning you … when thunderbird fails see if you can still access the mail server from your mobile phone. Also check the mail logs at the time thunderbird fails, this may give you an insite into what’s going wrong
No, I mean you have to log in with your own email and own password and you only see your own mailbox
I can’t find any mail logs in my log folder,
where can I find them?
Debain 12 thats in the journal use the webmin list log functions, I can’t remember which but if the one is empty the results will be in the other
You’re right. When I stop fail2ban, Thunderbird works, when I start the service Thunderbird no longer works.
if that is the case you need to find out which IP it is banning (is it your own IP? which could be a big problem or the IP of one of your users?)

i see in the jails status my IP in dovecot.
i remove my IP from banned list, when i try Thunderbird, my IP appears again
You need to touch base with the thunderbird forum to find out why thunderbird is suppling credentials that postfix/fail2ban is unhappy with. But as a quick fix white list the ip address you are connecting with (using thunderbird) in the relevant fail2ban jail, then you may be able to see what’s happening via the mail logs

I added my IP to whitelist list, now it seems to work, tested in thunderbird, iphone and roundcube
Now you can work out what’s giing wrong from looking at the logs, you will see in the fail2ban ban log when the ip has been allowed through due to white listing then just cross reference the mail log at that timeto see what actually happening
What is the worry ? The login to roundcube is just authing against the mail server so you may setup many instances however every instance of roundcube will be able to login to mail accounts if they are valid the only worry is if user/passwords from domain a became visable to users in domain b. Thats down to the sysadmin to make sure that doesn’t happen
