Resolve Debian 11 Telnet Mail Connection Timeout

Job ID: 37935964

Budget: $15 – $25 CAD

I'm currently experiencing a connection timeout when I try to resolve telnet mail.example.com 587. The exact message I'm receiving is 'Connection timed out'. On the other hand, telnet localhost 587 is functioning properly on Debian 11 with Postfix Dovecot running ISPConfig.

In addition, I'm also in need of help for some minor fixes. I'm not exactly sure if any recent changes in my network configuration or firewall settings have triggered these issues.

I'm looking for a skilled freelancer with vast experience in Debian and Postfix Dovecot who can troubleshoot and resolve these connection issues efficiently.

Skills and Experience Required:

- Proficiency in Debian 11 and Postfix Dovecot
- Experience in troubleshooting connection timeout issues
- Knowledge in ISPConfig and network configurations
- Experience in working with firewall settings
- Problem-solving skills
- Attention to detail
