How to Reduce Junk Emails in DirectAdmin Business Accounts

[iPwsite]

Hi everyone,

I’m using DirectAdmin for hosting, and recently several of my clients have complained that they’re receiving too many junk or spam emails in their business mailboxes ([email protected]/roundcube), ([email protected]/webmail)

I’d like to implement effective methods or configurations to reduce or block spam directly from the server side.

Could you please suggest the best practices or tools within DirectAdmin (or compatible plugins) to help control junk mail?

My goals are:

• Prevent spam before it reaches users’ inboxes
• Avoid false positives (important emails going to spam)
• Keep the setup lightweight and reliable

Any step-by-step suggestions or configuration examples would be appreciated.

Thank you!

To reduce junk emails in DirectAdmin business accounts, enable SpamAssassin and set a reasonable spam score threshold to move suspicious messages to the Junk folder. Strengthen filtering by adding reputable RBLs such as Spamhaus and Spamcop in the Exim configuration, and ensure that DKIM, SPF, and DMARC records are properly configured for all domains to authenticate legitimate mail. You can also enable greylisting to block automated spam bots and optionally use ClamAV for antivirus protection if server resources allow. Combined with basic user awareness—like marking spam and avoiding suspicious links—these measures will effectively minimize spam while preventing false positives and maintaining reliable mail delivery.

Greylising is not offered by DirectAdmin as of now, but it can be enabled in rSpamd: https://docs.rspamd.com/modules/greylisting/
