Troubleshooting Mailwizz and PMTA Server Errors

I have Mailwizz installed on several servers. We use PMTA. I already have one technician but I need another person to help me on occasion. For example, we've had several problems where the cron doesn't run or gets stuck. Another problem right now is I have a server sending slowly. Would you be interested in helping me out?

Ideal Skills and Experience:
- Extensive experience with Mailwizz and PMTA
- Strong troubleshooting skills
- Familiarity with server maintenance and cron jobs
- Ability to diagnose and rectify server errors
