After not finding proper solutions.
I started to go through #Postfix #Rspamd official Docs.
Then, I understand many configures.
Then i did some research on similar websites for mailserver checked that how they are doing it.

Migrated Postfix → PostgreSQL 🔄📦
No more flat files!
Now all virtual domains, users, aliases, & sender login rules live in a SQL DB.
Dynamic updates via my Node.js API
no Postfix reload needed!

Day 20:#100DaysOfInfra No coding today, but still learning!
Spent time understanding why databases matter in mail servers
SQL = speed, reliability
Mongo = flexibility, complexity
Sometimes, thinking > typing.
Back to building tomorrow

🚧Day 19 #100DaysOfInfra of building my own mail server + API
Tried integrating MongoDB with Postfix today.
Didn't succeed yet, no native support 😓
Looks like I’ll need a custom sync layer to bridge them.
Still, learned a LOT!

Explored using PostgreSQL & MongoDB for managing virtual domains, mailboxes & aliases.
PostgreSQL ✅ (native support)
MongoDB 🚧 (needs workaround)

❓Community: what open‑source tools or services do you use to generate/validate MTA‑STS & TLS‑RPT setups?Also curious about integrating ARC/BIMI into selfhosted mail infra. Suggestions?

Day 12/100 of #100DaysOfInfra 🛠️📧
Added support for multiple users per alias on the same domain🎉
Now [email protected] can be sent by admin@, ceo@, etc.
Used comma-separated entries in /etc/postfix/sender_login✅

Day 10 of my #100DaysOfInfra journey
Finally fixed cross-user spoofing! Now, no one can send mail as someone else unless explicitly allowed 🔐
Also got add/remove domain APIs working smoothly💥
#100DaysOfCode #Postfix #Dovecot #Linux #DevOps #SelfHosted #MailServer #OpenSource
🧠Still stuck on one thing:
Even after mapping sender_login_map, cross-user sending still works🤯(domain1 user can send mail of domain2 using right creds of their on domain)
Anyone faced this in Postfix+Dovecot combo?How did you fix it?

In today’s #JavaScript class, we explored built-in functions, writing custom #functions, increment expressions (#prefix & #postfix), and some string methods.
Learning by doing one step closer to clean logic! 💻
