Check the current version with <code>exim -bV | head -n 1<\/code>, run a cPanel update with <code>\/scripts\/upcp<\/code> (or repair just Exim with <code>\/scripts\/check_cpanel_pkgs --fix --targets=exim<\/code>), restart Exim with <code>\/scripts\/restartsrv_exim<\/code>, and send a test message.

It listens on the internet, so a security flaw in Exim can expose the whole server. Several serious Exim vulnerabilities have been found over the years, and attackers scan for unpatched servers quickly. Keeping Exim current is one of the most important updates on a cPanel server.<\/p>\n<h2 id=\"how-cpanel-delivers-exim-updates\" style=\"color:#0D1F3C;font-size:28px;line-height:1.25;margin:34px 0 14px;scroll-margin-top:90px;\"><i class=\"fas fa-terminal\" style=\"color:#00D4FF;\"><\/i> How cPanel delivers Exim updates<\/h2>\n<p style=\"margin:0 0 18px;\">cPanel builds and ships its own Exim package. Security fixes arrive through the normal cPanel update process, usually within a short time of an Exim release. You should not install Exim from source or from another repository on a cPanel server: cPanel would overwrite it, or mail could stop working.<\/p>\n<h2 id=\"step-1-check-your-current-version\" style=\"color:#0D1F3C;font-size:28px;line-height:1.25;margin:34px 0 14px;scroll-margin-top:90px;\"><i class=\"fas fa-terminal\" style=\"color:#00D4FF;\"><\/i> Step 1: check your current version<\/h2>\n<pre style=\"background:#0D1F3C;color:#EAF6FF;padding:18px 20px;border-radius:14px;overflow-x:auto;line-height:1.7;font-size:15px;\"><code>exim -bV | head -n 1\n\/usr\/local\/cpanel\/cpanel -V      # cPanel version<\/code><\/pre>\n<p style=\"margin:0 0 18px;\">Compare the Exim version with the latest security announcements from cPanel and Exim.
