Help - Permissions

Espresso uses Permissions to control spam in your mailbox. With Espresso, only approved messages get into your Inbox. Messages are automatically approved from people you know and trust. Using simple rules, you decide which email messages you want to see. Unknown senders are asked to identify themselves before their message is delivered. Legitimate senders will respond to this inquiry, but spammers cannot and will not respond.

Espresso does not use filters to eliminate spam. Nor does it rely on techniques like deep header analysis, anti-spoofing, heuristics, statistical analysis, Bayesian filters, or image decoding. It doesn't have to! Espresso is a sophisticated, permissions-based email client that blocks 100% of unwanted email as you have defined it.

Espresso delivers all the email you want to read and blocks all the email you don't want. It's that simple.

Addresses Tab
The Addresses tab is used to list email addresses from known and trusted senders that you want to receive email from.

Anytime you send an email to someone new, Espresso adds them to this list. So you're always up-to-date and assured to receive any email sent back to you. Espresso uses the simple rule (common sense really) that realizes if you send someone an email you most probably want to hear back form them.

Spammers rarely use legitimate email addresses. And if they do, it certainly would not be their own. Espresso doesn't look for addresses it doesn't recognize to determine if the message is spam. It looks for addresses from known and trusted senders to determine if this is an email you want to read.

Updates the list with a new email address. Only enter the address itself, for example:

As a general rule, you do not want to enter your own address. Sometimes spammers will try to disguise their messages by using your own address as the sender. Although, Espresso looks for this type of fraud, some spam may get into your inbox if you include your own address.

Deletes the highlighted address from the list.

Imports addresses from a comma-delimited list.

Imports the addresses from you Address Book in Espresso.

Before updating the list, Espresso will check to ensure the address isn't already in the list.

Domains Tab
The Domains tab is used to list all the known and trusted domains that you want to accept email messages from regardless of who the actual sender is.

Quite often this would be your work domain address, or the domain of other companies you do business with. It could be the domain of websites you visit often and order product from, websites which send you newsletters you want to read.

This is a very powerful feature of Espresso and saves you from having to enter each and every email address you regularly correspond with.

Updates the list with a new domain address. The domain address is the part of the address to the right of the "@" symbol. For example, the domain for the address "" is "".

It is best to enter unique ISP domain addresses here only. Do not enter common domains, such as, "" or "" as these domains are commonly used by spammers.

Deletes the highlighted domain from the list.

Imports domains from a comma-delimited list.

Before updating the list, Espresso will check to ensure the domain isn't already in the list.

Keywords Tab
The use of keywords is an important tool in controlling the messages you want to read... even from unknown senders!

At a very basic level, most people correspond to you on a personal level and will include you first name somewhere near the beginning of their message. The presence of your first name indicates that the message is from someone you probably know and want to read. This email message will go directly to your Inbox. It's that simple!

As another example, suppose you have an interest in railroads. If the email message contains the words "railroad" or "train" you would want to read it. Using those words in your keywords list will ensure those messages go directly to your Inbox! Perhaps your keyword list would contain words like "flower" or "garden", if that was your interest.

Espresso will search through the subject line, plain text and HTML bodies for the keywords listed. Do not include any words that are in your email address. It is always wise not to use your real or full name in your email address to preserve your identity. However, you may not have any control over this if your email address is already set.

Updates the list with a new keyword.

Deletes the highlighted keyword from the list.

Imports keywords from a comma-delimited list.

Before updating the list, Espresso will check to ensure the keyword isn't already in the list.

Blacklist Tab
Use the blacklist to ensure you don't receive messages from email addresses you know are sending spam, junk mail, or simply mail you don't want to read. Perhaps you have tried to get your email address removed from a website's mailing list without success. If so, add their email address to your blacklist and you'll never see another email from them.

The blacklist will work with both full email addresses or domain names.

Be careful not to add addresses from unknown senders in your junk mail folder. Many of these addresses may not be legitimate and you'll end up with a blacklist full of non-existent addresses.

Updates the blacklist with a new address or domain.

Deletes the highlighted address or domain from the blacklist.

Imports addresses or domains from a comma-delimited list.

Before updating the list, Espresso will check to ensure the address or domain isn't already in the list.

Settings Tab
The Settings tab lets you control how Espresso uses permissions and handles junk mail.

Use permissions to filter junk messages
Although this is the most powerful feature of Espresso, you don't have to use Permissions to filter junk messages if you don't want to. Simply turn it off.

Add outgoing recipients to permissions list
You should leave this checked to ensure anyone you write to will be able to send you a reply without it going to your junk mail folder.

Send Permission Notice to unknown senders
When you first start using Espresso, you may want to send a Permission Notice to unknown senders to ensure you haven't missed adding someone to your address or domain lists.

Once you're comfortable that your lists are in good shape, you may want to uncheck this option as all your known senders are listed. This is up to you. You define how you want to manage your mailbox.

Be aware that critics of permission-based, email management (also known as challenge/response) are concerned that challenging spammers to response only cycles more undelivered email through the internet. However, you have a right to know who is sending you email. Whether you send a permission notice or not, spammers are still going to keep doing what they do. The only way spammers will stop, is if they can't get through. Permission-based email is the only way to stop spammers cold.

It is common practice now for websites to send you an email verification notice when you sign up for an account, or newsletter, or to participate in a newsgroup, or whatever. Your email address will not be approved until you reply back or respond in some other way. It is not unreasonable for you to manage your Inbox the same way.

Espresso keeps track of permission notices pending verification and will not send another notice to the same address while the original address is still pending. This feature is enabled within Espresso to reduce the amount of unnecessary email messages sent through the internet. If an address is verified, then all emails with that address in the junk folder will be moved to the Inbox.

Automatically delete delivery failures
As spammers often use fake email addresses, the permission notice sent will bounce back with a delivery failure notice from you ISP. Espresso can recognize these delivery failure notices and automatically delete them. It is advisable that you enable this feature if sending permission notices.

Only filter obvious junk
This is a feature that will qualify messages from unknown senders to determine if it is junk mail based on a number of factors unique to spam type messages. If this feature is checked, only obvious junk mail will be moved to the junk folder. Other mail from unknown senders will be delivered to your Inbox.

Delete junk mail after
Deletes junk mail from the junk folders after the number of specified days.

Delete junk mail immediately
Messages from unknown senders is deleted immediately and moved to the trash folder.

Mark junk messages as read
Marks junk messages as read so you are not bothered with seeing unread messages in the junk folder.

Permanently delete junk mail
Permanently deletes junk messages. Messages are not moved to the trash folder and cannot be recovered.

Compact mailbox after deleting
Compacts the mailbox after permanently deleting junk messages.

Notice Tab
This is the sample notice that is sent out to unknown senders:

Thank you for your recent email, re: some subject here.

Unfortunately, your email address is not recognized as an approved sender by my email application, Espresso. Your message has not been deleted, but is being held pending verification of your email address.

To ensure your message is delivered, simply reply to this email with the verification code listed below in the subject line. This is a one-time process. All future messages from the email address listed below will automatically be accepted.

Address pending verification:
Verification code: 23ER5R43R56TE456

Please be aware that if you do not verify your email address by replying to this message within 2 day(s), Espresso will automatically delete your original message.
