Question

How to change logos in the webmail if Plesk Premium Email is installed?

Answer

There are two Plesk logos used in the webmail interface if Plesk Premium Email is installed:

• Logo in the top-left corner.

• The watermark which is used when no content is shown in several windows (message preview, address book preview etc.):

  

To change these for custom logos, use the following steps:

1. Prepare custom logos and upload these to the server.

   Note: The images should be in the SVG format.

2. Connect to the server using SSH and backup the original files:

   # mv /usr/share/roundcubemail/public_html/assets/skins/plesk/images/logo.svg{,.orig}
   # mv /usr/share/roundcubemail/public_html/assets/skins/plesk/images/logo-small.svg{,.orig}

3. Switch to the directory where the custom logos were uploaded and replace the logos with the uploaded ones:

   # cd /path/to/directory/with/uploaded/custom/logos/
   # mv logo.svg /usr/share/roundcubemail/public_html/assets/skins/plesk/images/
   # mv logo-small.svg /usr/share/roundcubemail/public_html/assets/skins/plesk/images/
