This feature is currently on the way and will be partly included
in version 0.5 (about April 1st :-)

0.5.0 will have only an email-checker (POP3, IMAP, LocalFolder
...), no preview of emails.

Email preview (and more) for for POP3 and possibly other
protocols is planned for 0.6.0 with various 0.5.x-releases in
between (currently planed for July the 5th :-).
