Mail servers · Webmail · Application SMTP
I set up and troubleshoot defined Mailcow or Stalwart environments, Roundcube webmail behavior, application SMTP routing, relay connections including MailBaby, and the Linux, DNS, SSL, proxy, and session context around them.

Focused Email Infrastructure capabilities
Each capability is scoped against the installed version, hosting, current behavior, and surrounding customizations before implementation begins.
Prepare a defined Linux environment for Mailcow and connect the required domain, mail, webmail, or application path.
Provision and configure Stalwart Mail Server for an agreed mail or application-relay workflow.
Trace webmail redirects across host, base URL, SSL, proxy headers, cookies, sessions, and application configuration.
Connect supported websites, PHP applications, or mail platforms to an agreed SMTP relay, including MailBaby.
Investigate the surrounding infrastructure when the visible mail symptom begins outside the mail application itself.
Clear service boundaries
These boundaries preserve the difference between evidenced Email Infrastructure work and a broader service that has not been claimed.
The matched portfolio cases show adjacent SMTP, DNS, SSL, Linux, proxy, and PHP-platform work. They are not presented as completed Mailcow, Stalwart, Roundcube, or MailBaby project outcomes; those capabilities come from separately confirmed experience.
Configuration can support a correct send path, but inbox placement, reputation, blocking, throttling, and provider policy are controlled by multiple external systems.
DNS ownership, server access, relay accounts, ports, reverse DNS where applicable, and provider restrictions must be available or coordinated by the client.
Changes to a live mail environment require explicit backup, migration, mailbox, retention, and rollback expectations before material reconfiguration.
Mailcow, Stalwart, Roundcube, SMTP relay, and MailBaby capabilities are based on confirmed experience. Matched cases are deliberately described only as adjacent SMTP, DNS, SSL, Linux, proxy, and PHP-platform evidence.
Email Infrastructure project evidence
Matches are selected from project titles, summaries, categories, and technology lists—not from unrelated generic case studies.
Configuration and repair of Cloudflare DNS, SSL, CDN, and origin connectivity for an existing website or PHP platform.
Read case study
Focused repair of WoWonder PHP, MySQL, API, login, SMTP, or post-update issues within the supported platform scope.
Read case study
A layered mail-delivery setup connecting a PHP application or mail platform to an authenticated relay with TLS, DNS-aware configuration, logging, and failure investigation.
Read case studyRelevant development services
Setup and troubleshooting for Mailcow, Stalwart Mail Server, Roundcube, SMTP relays, application mail routing, and MailBaby.
Fresh Ubuntu or Linux web-stack provisioning and controlled migration for an agreed PHP, WoWonder, or PlayTube application.
Linux hosting setup on AWS EC2, DigitalOcean, or Vultr; Apache or Nginx configuration; Cloudflare, SSL, storage, release support, and practical troubleshooting.
Systematic diagnosis of PHP errors, JavaScript failures, database issues, broken integrations, and inconsistent production behavior.
Provision a defined web application stack on fresh Linux infrastructure and configure its reverse-proxy or load-balancing request path.
Email Infrastructure delivery process
Credentials are requested only after the scope and access requirement are understood, using an agreed secure channel.
Map the domain, sender, application or mail client, server, relay, webmail, DNS, proxy, and recipient behavior involved.
Review sanitized errors, headers where appropriate, logs, redirect behavior, DNS records, ports, TLS settings, and relevant platform configuration.
Determine whether the failure belongs to Mailcow, Stalwart, Roundcube, the PHP application, SMTP relay, DNS, SSL, session, or proxy layer.
Apply the focused setup or correction while preserving unrelated mailboxes, domains, and application behavior.
Test the agreed login, webmail, application send, relay, redirect, or receive path and document remaining provider dependencies.
Email Infrastructure FAQ
If the exact issue is not covered here, send the current platform behavior and I will say whether it fits the represented work.
Email Infrastructure inquiry
Share the platform, domain and DNS context, current symptom, intended sender or webmail path, and sanitized error details. Keep credentials out of the public contact form.
