Hi, I have an issue on sending remarkable amount of e-mail in which queued e-mails are reach almost 20000 emails. considering below link, I want to know if  these parameters are functional and how can I value them in postfix conf file?

http://www.postfix.org/TUNING_README.html#proc_limit

default_destination_recipient_limit
smtpd_recipient_limit
smtp_connect_timeout
smtp_helo_timeout
smtp_destination_concurrency_limit
default_destination_concurrency_limit

However, to what extent using SSD hard is helpfull? how about CPU?

The most effective solution might be disabling spam/virus scanning for the (TRUSTED) account you used to send bulk emails, it will speed up the sending A LOT.

Yes.

With iRedAdmin-Pro, you can go to user profile page, click tab "Spam Policy" and disable spam/virus scanning there.

Without iRedAdmin-Pro, it's a little hard to write SQL command to update spam policy in SQL table "amavisd.policy". sad
