E-mail accounts contain a lot of important information. Someone can get your e-mail password and gain access to your e-mails. At the moment, the attacker can as well login to vexim and change your password that you won't have access to your mails any more (and you cannot change the password yourself). With two-factor authentication, the attacker can still access all e-mails but he cannot change password or delete other users (in case of an admin-account).
In some webmail solutions (e.g. Roundcube), two-factor authentication can be activated. In my opition, it makes no sense because mails can be access via imap.
