How to Change the backups destination folder for the system and for the clients also?

Is there a way for Kloxo to work with a external database server?
For example, if Kloxo is installed in a DigitalOcean's droplet or a AWS Instance or in Azure or even if I have a dedicated server for database only, I would like to use the external database an not the one that is installed in the system.

Kloxo-MR Tips and Tricks / Optimization and best practices
« on: 2020-02-28, 11:27:38 »
What optimizations could be made to make kloxo-mr be more optimized for memory/cpu consumption? Found some optimization tricks but too old as for 6.5.
There are many components in DNS, Webserver that I'v neve heard of and also in cache.
I use Apache and Bind, no caching yet as don't know what it can give to the system (I know what it is but  don't know how to use it).

So guys, what are you using in your servers?

P.S. Use only Apache, becouse of some Prestashop websites and it is hard to make it work on Nginx or others.

Kloxo-MR Tips and Tricks / Reinstall roundcube
« on: 2020-02-28, 11:22:38 »
I've found out that my rouncube is not working, it exists some how but not seent by kloxo and when I execute 'sh /script/fixwebmail' there are some messages that say that some files could not be found.
How to reinstall it?

Could anyone explain how master-slave in kloxo works?
I need to know:
- could servers be in different notworks (e.g. in different clouds, onw in Amazon and another in Digitalocean)?
- how DNS works between both? are they replicated?
- what about accounts (with databases and websites) registered on one server, are they replicated too?
- and also the question about emails?

Some strange things happened few hours ago.
I do can connect to mysql from console "mysql -u root -p" but when I do "sh /script/cleanup" I get following errors:
Code: [Select]
Update Kloxo database
- Update process
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
- Fix mail-all services
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

When I try "sh /script/reset-mysql-root-password <SomeNewPassword>" I get
Code: [Select]
Stop MySQL service...
MySQL ROOT password reset...
Start MySQL service...
191119 03:49:37 mysqld_safe A mysqld process already exists

I also tried to change password using that post https://forum.mratwork.com/kloxo-mr-releases-and-announcements/(tip)-reset-password/ but still same errors.

That error "Access denied for user 'root'@'localhost'" I also receive when I  do "sh /script/fixmail-all" and "sh /script/fixvpop" and some actions from the panel.

How to fix that?

How to change the main domain name that kloxo was installed above?

Kloxo-MR Technical Helps / DigitalOcean droplet with Kloxo
« on: 2019-04-23, 15:02:08 »
Does anyone knows any setup tips for making kloxo-mr work on Digitalocean droplet?
Did installed and it works, but when accesing subdomains (like webmail.mydomain.tld or cp.mydomain.tld) or other domains registered in kloxo it redirects to to the main server domain.
Also did dns configurations like mentioned here (https://www.digitalocean.com/community/tutorials/how-to-create-vanity-or-branded-nameservers-with-digitalocean-cloud-servers).

Does "Blocked IP Addresses" definitively blocks IP's so no any connection attempts could be made from those IP's at any services (smtp, imap, pop, ssh, etc.)?
I'm asking because I've blocked some IP's but still get tries to connect to smtp from them.

Kloxo-MR Technical Helps / Lot of error with mail server
« on: 2018-03-14, 15:28:46 »
Having just 1 domain and ~50 emails (and more to come) I get a lot of errors from users in using email with roundcube or thunderbird.
In a few words problems are: "imap folder is not accessible", "can not save message in sent folder", "error on connecting to mail server and always requesting the password", and others.
I've tried to increase the number of limits and instances to smtp and imap.
I did some tweaks in dovecot to performance.
But none of that solved me.

Some observations done on working processes and found that very often "sendlimiter" consumes >99% of CPU. (I have 3 CPU on that server and 16GB of RAM).

Does anyone know how to fix that?
As a temporary solution, but not the fix, i need to restart the server every half a hour, but again - this is not a solution for a system with 100-150 emails that will come.
