I've been setting up my own VPS for an e-commerce, as well as a mail server.

In order to setup the e-commerce, mysql and apache is running.

In order to setup the mail server, I've installed postfix. However, after installing postfix, several days passed and I figured out something:

  • Some mails are delayed / blocked because of ClamD email checks.
  • ClamD is using about 50% of my VPS resources. I've checked if those values were normal, and a lot of users complain about the same.
  • The easy way, would be to remove ClamD / Stop it. However I do not want to keep an unsafe mail system.

I'm not very used in setting up mail environments, so I'm looking for tips about:

  • What happens if I do not use antivirus for those mail checks?
  • Is there an other good enough antivirus to check for those mails?
  • In case I decide to not use any antivirus, should I setup some grey/blacklisting in order to prevent spam sent / received?

Sorry if my question is a little bit abstract.

From the OP comment, the mail server only handle 2 email accounts. For a small system like this, you can safely turn off the clamD. In this situation, I prefer to alternative solution like educate your user about email security rather than place an antivirus daemon to scan your email. Antivirus will help you in the system with many user involving and you can't educate them one by one.

Instead on virus, another challenge you faced is spam. The solution like properly-configured postfix and external solution like grey/blacklisting (via postgrey for example) will help you reduce spam in with little cost on system performance.
