'''Perform the following steps:''' #Perform a search on the roundcube application in order to access the website.#Either Download the "zipped tarball" from their website from a direct link or use the wget command to download directly from a download link (This part may take some effort depending on the Sourceforge website).#Extract the "zipped tarball" and rename the generated directory that contains download source code to: '''webmail'''.#In the directory now named "webmail", there will be a file named '''INSTALL''' which will walk you through the rest of the Roundcube installation.<br><br>Some installation tips to consider: ::* Be careful about copying & pasting the MySQL setup part: take time and pay attention to detail: do not try to "rush it".::* You will need to install several additional Apache modules including: '''php-xml''', '''php-pdo''', and '''php-mysql'''.::* Don't forget to set the password in the roundcube configuration. <ol><li value="3">Note that both of your IMAP and SMTP servers are on different machines (i.e. not on vm1). Therefore, you will need to set the following options for Roundcube:</li></ol> ::* '''$config['smtp_server']'''::* '''$config['default_host']'''::* '''$config['default_port']''' :::'''NOTE:''' The last <u>two</u> entries above refer to your IMAP server <ol><li value="4">You should be able to test the configuration in your Roundcube installer after completing Step 3.</li><li>Try to test if the roundcube webmail application is working by sending and receiving e-mail messages.</li></ol>
