How can I send an e-mail using Roundcube?
Click on the "Compose" button. After composing your e-mail with the recipient's e-mail address(es), subject, and message, you can send it by clicking the "Send" button. If you want to finish your e-mail later, you can save your message to the "Drafts" folder by clicking the "Save" button. When you decide to send your saved e-mail, click on the "Drafts" folder and find the e-mail you want to continue composing.
