Afraid of viruses? You receive spam mails? Postprüfer checks your mails
directly on the server! There is no download necessary! It shows you a list
of available mails with some useful information about them. You may delete
undesired mails directly on the server or you edit lists in order to let
MailSecurity do it automatically. The software is also able to check all
of your accounts for new mails (automatically, as a background task).
