<\/p>\n\n\n\n

If your primary mail server IP address<\/strong> is blocked by spam-checking services (e.g., BARRACUDA, SORBS-SPAM<\/strong>), the best solution is to change the outgoing mail server IP address<\/strong> in Plesk<\/strong>.<\/p>\n\n\n\n

On a cPanel server<\/strong>, this is done via \/etc\/mailips<\/code>. In Plesk<\/strong>, you need to update the \/var\/qmail\/control\/smtproutes<\/code> file.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Step 1: Check Hosted Domains on the Server
<\/strong>Before modifying the mail server IP, list the domains hosted on the server by running:<\/p>\n\n\n\n

cat \/var\/qmail\/control\/rcpthosts<\/mark><\/p>\n\n\n\n

\ud83d\udd0d Example Output:<\/strong><\/p>\n\n\n\n

domain1.com
domain2.com
domain3.com
domain4.com
domain5.com<\/mark><\/p>\n\n\n\n

Step 2: Create or Edit the smtproutes File
<\/strong>By default, the smtproutes<\/strong> file does not exist<\/strong> in Plesk. You need to create it manually.<\/p>\n\n\n\n

vi \/var\/qmail\/control\/smtproutes<\/mark><\/p>\n\n\n\n

Step 3: Assign a New Mail Server IP Address<\/strong><\/p>\n\n\n\n

Add the new outgoing mail server IP<\/strong> in the following format:<\/p>\n\n\n\n

<\/p>\n\n\n\n

domain1.com:192.168.0.2
domain2.com:192.168.0.2<\/mark><\/p>\n\n\n\n

\u2705 Replace<\/strong> 192.168.0.2<\/code> with your actual new IP address<\/strong>.
\u2705 Replace<\/strong> domain1.com<\/code> with your actual domain name<\/strong>.<\/p>\n\n\n\n

Step 4: Restart Qmail to Apply Changes<\/strong><\/p>\n\n\n\n

After updating the smtproutes<\/code> file, restart the qmail<\/strong> service:<\/p>\n\n\n\n

\/etc\/init.d\/qmail restart<\/mark><\/p>\n\n\n\n

Final Check:<\/strong>
\u2714 Verify outgoing emails use the new IP<\/strong> by checking the mail logs:<\/p>\n\n\n\n

tail -f \/var\/log\/mail.log<\/mark><\/p>\n\n\n\n

\u2714 Use an email header analysis tool<\/strong> to confirm that outgoing emails are being sent from the new IP.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Benefits of Changing the Mail Server IP:<\/strong><\/p>\n\n\n\n

\u2705 Avoid blacklisted IPs<\/strong> to improve email deliverability.
\u2705 Prevent outgoing emails from landing in spam folders.<\/strong>
\u2705 Enhance email reputation and ensure reliable mail flow.<\/strong>
