By default SMTP usually uses port 25, but as sometimes ISP\u2019s may prevent the port 25 for access. In such circumstances we need to set up an alternate port of SMTP. This can be done on a cPanel servers as follows:<\/p>\n

Login to the WHM.<\/strong><\/p>\n

Navigate to Main >> Service Configuration <\/strong>.<\/p>\n

Click on service manager<\/strong>.<\/p>\n

Navigate to the section which says \u201cexim on another port\u201d.<\/strong><\/p>\n

Click on the \u201cEnabled\u201d box besides the setting and enter the Alternative SMTP Port in the box and apply changes.<\/p>\n

Now make sure\u00a0the alternative port is enabled on the server firewall.<\/p>\n

For this open the file \/etc\/csf\/csf.conf<\/strong> on the server and add the port in the TCP_IN, TCP_OUT, UDP_IN, UDP_OUT<\/strong> sections. Save the firewall and restart the firewall.<\/p>\n

Now the alternative SMTP<\/strong> port is configured for your server.<\/p>\n
