Espresso is a powerful permissions-based email client designed to completely
eliminate spam as you define it from your Inbox.
Espresso's unique email filtering system is based on common sense. Everyone knows from
whom they want to receive email. Anyone else who sends you messages is sending you
junk, otherwise known as spam. Espresso does not filter junk. It only looks for messages
you want to receive based on simple, yet powerful rules. Using a number of options
available, you decide how to handle messages from unknown senders.
In addition to controlling spam, Espresso offers the following features to control
how you manage email:
- lightweight and portable email client
- powerful junk mail filtering based on permissions
- filter messages using regular expressions
- ability to add notes to individual messages
- hide private messages from prying eyes
- automatically blind copy on all outgoing mail
- easily flag important messages
- supports POP3, IMAP4, HTTP protocols
- preconfigured for easy setup of Hotmail and GMail
- built-in backup and restore mailbox
- powerful spell-checker for outgoing messages
- choose to save or delete messages when you send them
- automatically mark messages as read when moved to trash
Lightweight and Portable
Espresso was designed to be both lightweight and portable. In order to maintain it's
lightweight architecture, Espresso supports all the expected email requirements, but
eliminates all the unnecessary "fancy" features which tend to make the application
chunky and add no real value. As a result, Espresso requires just over 2MB of hard disk
space (plus the size of the mailbox), and occupies about 7MB of RAM with a average size
mailbox loaded. This lightweight feature gives Espresso amazing speed.
It was essential that if the email application was to be lightweight, it also had to
be portable. This meant that all the configuration settings, profiles and mailbox had
to be contained within the same directory. Espresso accomplishes this, allowing the user
to easily install the application on any portable device which can be attached to a
computer to access mail via the internet. In addition to installing on a hard drive, Espresso
can be installed on any flash media, USB key or even an MP3 player.
Junk Mail Filtering
Espresso's powerful junk mail filtering system is based on the simple fact that everyone
knows who they want to receive email from. Anyone else who sends you something is sending
you junk, otherwise known as spam or unsolicited email. Espresso uses a sophisticated filter
system to pass only the mail you want to receive to your inbox.
Most of the junk filters in use today employ various methods to determine if the
incoming message is likely to be junk based on a statistical analysis of the contents. This
method, of which the Bayesian Filter is the most popular, requires constant training and
retraining to achieve acceptable results. The inherent problem with most junk filters is
that spammers constantly find ways to trick the filters. And the filters can easily be
fooled because they are looking for junk, or spam.
Espresso simply and successfully looks for messages that are NOT junk. On a very basic
level, you want to receive email from everyone in your address book. So any messages
from these people don't need to be analyzed. In addition to filtering acceptable messages
based on email address, Espresso goes further by accepting email from whole domains (ie:
work, or newsgroups you belong to), and keywords, but blocks messages from anyone on a
Keywords are an important and powerful element to identify good mail. For example, most
people sending you email will use your first name near the beginning of the
message. As long as your first name is not part of your email address, any occurrence of
your first name would identify a message from someone you know. As another example, suppose you
have an interest in railroads, any occurrence of the word railroad, or train, would identify
a message you want to read. It's that simple!
Espresso's method of filtering for acceptable email is called Permissions. It's also
commonly known as a challenge and response system. To learn more about how Espresso uses
and improves on this method to ensure only the email you want to receive reaches your inbox,

Filter Using Regular Expressions
Regular expressions are a powerful method of looking for patterns in the text, rather
than looking for specific text to match. It is advised that you only filter using
regular expressions if you are familiar and comfortable with this method.
Notes can be added to each message using the main menu, toolbar or popup menu while in the
main screen. You can use notes to keep track of replies, or just general info regarding
the status of the message. Great for messages pending further action.
Hide Private Messages
Messages can automatically be marked as private when received and put into a hidden
folder only accessible through a special key combination and/or password. Use filters
to mark messages as private based on any number of criteria. Great tool for those who
like to keep their email client open all day, or minimized to the system tray.
Auto Blind Copy
In situations where you are required to blind copy someone on all your correspondence,
Espresso can be set up to automatically blind copy pre-determined individuals. This could
be a boss, or even yourself at another address.
Flag Important Messages
Messages can be quickly flagged using the main menu, toolbar or popup menu. Or simply
click on the flag column next to the message you want to flag. Clicking again toggles
the flag status.
Supports POP3, IMAP4 and HTTP
Connect to any email account using one of the three available protocols: POP3, IMAP4 or
HTTP. IMAP4 support provides for downloading messages into the local mailbox, or sending
new messages. As such, implementation of IMAP4 treats messages in much the same way as
POP3 server messages. Espresso was designed to control junk mail in your local inbox. True
IMAP4 reads new messages directly from the server. Any junk mail would already be in your
inbox on the IMAP4 server and no benefit would be realized.
Hotmail and GMail
Espresso's account setup is pre-configured to connect with either Hotmail or GMail, eliminating
the need to remember confusing port settings, server addresses or security settings. Simply
input your user ID and password for either Hotmail or GMail and your ready to start receiving
and sending messages to your local mailbox.
Backup and Restore
The ability to backup and restore mailboxes is built directly into Espresso. No need to
purchase third party software or figure out where the mailbox is hidden to manually backup.
Ideal when planning a major change to the mailbox, such as importing messages from an unknown
or unreliable source.
Never by embarrassed about your spelling again. Espresso can be set to spell check all your
messages before sending. The spell checker is available in many languages for free.
Save / Delete When Sending
Not every message you send needs to be saved. Why use up mailbox space when just sending
a quick note to someone. You can configure Espresso to prompt you to save messages when
you send them.
Mark Trash As Read
Sometimes it is quite easy to identify messages as trash without have to read the whole
message. Just a quick "Delete". If viewed for less than 5 seconds, the message will
still be marked as "Unread". You can configure Espresso to automatically mark messages
move to the trash as read.
