THE FILTER VERBS
Excerpted from the Eudora Help Manual

FOR EUDORA 5.1 and 5.2 (Eudora 5.2 has three additional verbs)

The available verbs for filter matching in Eudora 5.1 for Windows

The available verbs for filter matching in Eudora 5.1 for Windows:

Contains
Doesn't Contain
Is
Is Not
Starts With
Ends With
Appears
Doesn't Appear
Intersects Nickname
Matches Regexp (Case Insensitive)
Matches Regexp


Definitions:

contains or doesn’t contain - If the specified header item contains or does not contain the text string, filter the message. Other text is allowed to surround the text string.

is or is not - If the specified header item is or is not an exact match of the text string, filter the message.

starts with or ends with - If the specified header item starts with or ends with the text string, filter the message. The starts with item refers to the first non-whitespace character after the colon, so any spaces after the colon are ignored.

appears or doesn’t appear - If the header item appears or does not appear in the message, filter the message (the text field is ignored). This is useful for filtering messages based only on the types of fields they contain. For example, some messages contain a Reply-To: header, some don’t.

intersects nickname - If the text string is included in a nickname, whether it is a full address or a nickname within the nickname, filter the message. In other words, the filter looks in all of your address books for the nickname that appears in the header of the message. If it finds it, it filters the message accordingly.

matches regexp (case insensitive) (Sponsored and Paid modes only) - If the specific item matches the regular expressions characters with case insensitivity, filter those messages.

matches regexp (Sponsored and Paid modes only) - If the specific item matches the regular expressions characters, filter those messages.

 

THE FOLLOWING VERBS ARE ONLY AVAILABLE IN EUDORA 5.2

doesn’t intersect nickname - If the text string is not included in a nickname, whether it is a full address or a nickname within the nickname, filter the message.*

intersects address book - If the text string or nickname is included in any one of your address books, whether it is a full address or a nickname within the nickname, filter the message. In other words, the filter looks in all of your address books for all nicknames. If the nickname that appears in the header of the message is in the address book, Eudora filters the message accordingly.*

doesn’t intersect address book - If the text string or nickname is not included in an address book, whether it is a full address or a nickname within the nickname, filter the message.*

* In Eudora 5.2.09 Beta, the Intersects Address Book filter verbs seem to have a bug that requires the email addresses to be in lower case to match. The 5.2.1 beta appears to have fixed this problem.
