The Hermes application was designed to be a small mail program that can connect to your mail server. You can see the message sizes before retrieving them with your favorite mail program.
It enables you to delete messages you don't want. You can also see the source of message headers, so you know the who is the author of the mail. Some (or all) of text of the message can be seen, to enable you to decide whether to accept or delete. Supports up to 10 email e-mail accounts.
