Topic: How to properly disable sogo and keep mail part

- iRedMail version: 1.0-beta2 MARIADB edition
- Deployed with  downloadable installer
- Linux/BSD distribution name and version: debian10
- Store mail accounts in MySQL backend
- Web server: Nginx

Hi,

due to too many issues, I migrated to a better known software: owncloud instead of sogo.

So I ran :

systemctl stop sogo
systemctl disable sogo

But after running 'mysqltunner.pl', I saw that I have errors in MySQL logs :

2020-01-08  0:37:03 138645 [Warning] Aborted connection 138645 to db: 'sogo' user: 'sogo' host: 'localhost' (Got an error reading communication packets)

What is trying to call sogo db ?
How can I disable properly sogo ?

Regards

Re: How to properly disable sogo and keep mail part

SOGo daemon user has 2 cron jobs, you need to disable them too.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

But I see only one line in root crontab for backup, and in /etc/cron* nothing to connect to MySQL.

My crontab :

I still have tons of errors in MySQL logs 2 times, every minutes :

Re: How to properly disable sogo and keep mail part

I said "SOGo daemon user" has the cron job, not root user.
You should run "crontab -l -u sogo" to check it.
