Topic: Hardware resources requirement

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release):
- Deployed with iRedMail Easy or the downloadable installer?
- Linux/BSD distribution name and version:
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro?
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

Is there any suggestion or sizing plan document for iRedMail system?
I am planning a mail system that will host more than 10,000 mailboxes, what's the suggested hardware resources design for such a system?
Furthermore, how about the hardware resources design if hosting more than 30,000 mailboxes?

Thanks,
Steven

Re: Hardware resources requirement

Hardware spec is not based on number of mailboxes, but the sent + received emails per day. For example, 1 million accounts but no emails sent/received ...

So the question is, how many emails will it send and receive per day?

I am not sure about the exact number of emails send and receive per day.
Let's assume that average 5 emails send and receive per user per day,
so for 10,000 users, it will be 50,000 emails per day, and for 30,000 users, it will be 150,000 emails per day.

Looking forward to your reply.

Many thanks for your help.

Steven

If it's really 150,000 messages, 16GB RAM might be a little tight, 32GB RAM is better.

Unfortunately, no.
