Fix Postfix Email Errors FAS + Automate OVH + Cloudflare DNS with Ansible
#Postfix #Roundcube #Dovecot #MailServer #SMTP #SSLTLS #LetsEncrypt #Certbot
If your email server suddenly stops sending/receiving, Postfix “looks running” but SMTP fails, and you suspect SSL/TLS certificate issues, this video is for you. We walk through a real troubleshooting + setup session: Postfix + Dovecot + Roundcube, SSL/TLS checks, DNS records on Cloudflare, and how to automate the whole mail-stack deployment with Ansible on OVH—including IPv4 + IPv6 (dual stack), firewall rules, and SMTP reliability.
Copy of Daily Meeting for Crawl…
You’ll learn:
Why “Postfix is running” doesn’t always mean email will send
The most common causes of SMTP connection failures (SSL/TLS + permissions + DNS)
How to correctly set A/AAAA records and avoid common DNS update mistakes
How to set up Roundcube webmail properly (Apache/PHP/Dovecot + database step)
How to structure an Ansible playbook for mail sending setup (domain, TLS, firewall, DNS, Postfix)
Why you must encrypt credentials (Ansible Vault best practice)
