hello,
i want to deploy an email server which is suppose to receive 5000 email per hour max and 20000 a day in total. is postfix and dovecot can handle this much incoming email traffic smoothly by default setting with cwp pro? or do i have to fine tune some setting/parameters to optimize the mail server performance?
kindly suggest if cwp pro can be used to manage email server on large scale? how stable is it ? did someone tested it on a busy server.
Regards,

Stability is based on system specs. 4GB ram is the minimum to run all of the spam/antivirus programs. That many emails, I would suggest 8GB ram w/ 4GB swap. Aside from that, postfix/dovecot should run just fine. If you don't need the websites, you can disable apache.
Thanks for your reply. For this project I will have 8 cores 30Gb ram 800GB ssd drive with unlimited monthly bandwidth @600 Mbit/sec port. With this much RAM do I still need swap????
I am always confused which domain to put in hostname, should it be the main domain for which I am setting up the email server for? Or it should be any other domain to access the server only?
Should I put mydomain.com as hostname or make it server.mydomain.com? And then how to Configure ssl for the hostname so that access to cpanel for admin and user are secured via ssl.
Hostname needs to be somesubdomain.domain.com. server. srv. basically anything as long as there are two dots.
with that much ram, you do no need swap.
Upon installation, CWP should get a valid certificate from letsencrypt. If you want to buy a cert, you can install that via the CWP admin interface.
thanks for your reply. i will do the installation and will share with you the results :)
