Topic: Help with increasing Postfix speed?

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 0.9.8
- Linux/BSD distribution name and version: Ubuntu 16.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Ngnix
- Manage mail accounts with iRedAdmin-Pro? NO
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

More Info:

With my current config I am able to send 40k mails/hr. I believe performance can be improved. Any help?

- Server hardware spec?
- How did you send email? e.g. perform smtp auth for each sent email? or using a mailing list manager like 'mlmmj' (integrated in iRedMail).

Re: Help with increasing Postfix speed?

Few small changes will speed up a little bit:

- Perform one smtp auth to send multiple emails (if possible).
- Use mailing list to send same email to multiple recipients (if possible).
- Disable spam/virus scanning for outgoing emails will speed up a lot.
