I have Mail client installed on my Ubuntu server. I know how to send email from terminal and I know how to read email, if I get it. But - how can I enter in Mail client if I don't have any new mail. To be more understandable - I want to enter the part where can I see commands like alias, alt, copy, cd, ch, dec, delete ... Or maybe - how can I find (read) all sent mails?
UPDATE: I use Mail (GNU Mailutils 2.99.99). If I have a new mail and write "mail" then it opens a program where I can read an email (with inserting a number written before name and subject). I can also type "?" to get more help, where I can see many options (write, save, send, delete ...). This is ok. But - if I don't have any email waiting for me and if I write "mail" in terminal, I get only message "No mail for xxxx". It stays in Linux terminal, but I'm sure, it can open a Mail program somehow.
