Filter Support

The sophistication of the underlying Thunderbird filter system has not yet progressed to match that of classic Eudora (i.e. ≤E7.1). Because of this, some of the filter conditions, operators, and actions will not be imported, though the filter containing them will be imported.

The following charts diagram the classic Eudora filter system elements and the state of their support in Eudora 8 and beyond, given in the order in which they appear in the respective application.

Mail Headers

Mail Header	Supported in E8	Label in E8
To:		To
From:		From
Subject:		Subject
Cc:		Cc
Reply-To:		Reply-To *
«Any Header»
«Body»		Body
«Any Recipient»		Intersects From, To, Cc or Bcc which adds the From header which was not supported in the ≤E7.1 selector
«Personality»
«Junk Score»

* Added E8's Customize feature which allows you to add any mail header selector not included by default; Reply-To can be used as a syntax reference for other custom header selectors

Eudora 8/Penelope adds the following header selectors not found in classic Eudora:

• Priority
• Status
• To or Cc
• From, To, Cc or Bcc
• Age in Days
• Size (KB)
• Tags

Logical Conditions

Logical Conditions	Supported in E8	Label in E8
contains		contains
doesn't contain		doesn't contain
is		is
is not		isn't
starts with		begins with
ends with		ends with
appears
doesn't appear
intersects nickname
doesn't intersect nickname
intersects address book		is in my address book *
doesn't intersect address book		isn't in my address book *
matches regexp (case insensitive)
matches regexp

* Only appears when a recipient header has been selected.

Logical Operators

Logical Operators	Supported in E8	Label in E8
ignore		n/a *
and		Match all of the following
or		Match any of the following
unless		n/a †

* This operator is non-explicit in E8 since the number of entries in the Header interface is dynamic, as opposed to ≤E7.1 where there were two fixed header selectors, the second of which should be explicitly ignored if it wasn't utilized.

† The importer should generate a warning if the second filter parameter cannot be properly negated to meet the unless condition.

Filter Actions

Filter Actions	Supported in E8	Label in E8
Make Status		Intersects Mark as Read only. ≤E7.1 also allowed Unread, Replied, Forwarded, and Redirected
Make Priority		Mostly intersects ≤E7.1's Set Priority To, except for the omission of the Raise and Lower priority settings
Make Label		Tag Message
Make Personality
Make Subject
Play Sound
Speak
Open
Print
Notify User
Notify Application
Forward To		Forward to
Redirect To *
Reply with		Reply with Template
Server Options		Split into two separate top level actions – Delete from POP Server and Fetch from POP Server – instead of making those same actions available as submenu selectors
Copy To		Copy to
Transfer To		Move to
Junk		Set Junk Status to allows for a Not Junk setting which was not available in ≤E7.1
Skip Rest		Stop Filter Execution

Eudora 8/Penelope adds the following filter actions not found in classic Eudora:

• Add Star
• Delete Message

Delete Message could be accomplished in ≤E7.1 by simply transferring to Trash, but did not exist as a unique action.

* In classic Eudora, the process of using filters to automatically redirect messages was referred to as Turbo Redirect, as opposed to invoking the redirect command manually from the toolbar button or Message menu.
