ISPConfig & Mail Server

Remote ISPConfig and mail server support

Remote technical support for private individuals who need help with ISPConfig, Postfix, Dovecot, mail delivery, SMTP, IMAP, mail authentication and mail-related DNS configuration.

This service focuses specifically on ISPConfig environments and Linux mail servers: problems involving mailboxes, domains, delivery failures, authentication, queues, TLS and the interaction between the mail stack and ISPConfig.

Typical issues I can help with

• ISPConfig configuration and troubleshooting
• Mail domains and mailbox problems
• Postfix delivery failures
• Dovecot IMAP and authentication issues
• Messages stuck in the mail queue
• SMTP connection and relay problems
• TLS certificate and encrypted mail connection issues
• SPF, DKIM and DMARC configuration problems
• Mail-related DNS errors
• Incoming or outgoing mail failures

What this service does not cover

General Linux configuration problems belong under Linux Server Support. Nginx, PHP-FPM, MariaDB, Redis and reverse proxy issues are handled through Nginx & Web Stack.

General routing, VPN and network connectivity problems belong under Network & VPN. This service is specifically for issues whose main cause is related to ISPConfig or the Linux mail server stack.

How the service works

Support is provided remotely and by appointment. Before any paid work begins, I review the issue and confirm whether it falls within the scope of this service.

The selected session covers up to the purchased support time. If additional time or more extensive work is required, I will explain it clearly and continue only after your approval.

Follow the message through the mail stack

Mail problems can involve several layers at once: DNS, SMTP, authentication, queues, TLS, filtering and mailbox access. I trace the actual delivery path to identify where the failure occurs instead of changing unrelated settings.

This is a remote technical support service for private individuals.
