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 OSE, given in the order in which they appear in the respective application.
|Mail Header||Supported in OSE||Label in OSE|
|«Any Recipient»||Intersects From, To, Cc or Bcc which adds the From header which was not supported in the classic Eudora selector|
* Added by Eudora OSE’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 OSE adds the following header selectors not found in the classic application:
- To or Cc
- From, To, Cc or Bcc
- Age in Days
- Size (KB)
|Logical Conditions||Supported in OSE||Label in OSE|
|doesn’t contain||doesn’t contain|
|starts with||begins with|
|ends with||ends with|
|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)|
* Only appears when a recipient header has been selected.
|Logical Operators||Supported in OSE||Label in OSE|
|and||Match all of the following|
|or||Match any of the following|
* This operator is non-explicit in Eudora OSE since the number of entries in the Header interface is dynamic, as opposed to classic Eudora 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||Supported in OSE||Label in OSE|
|Make Status||Intersects Mark as Read only. Classic Eudora also allowed Unread, Replied, Forwarded, and Redirected|
|Make Priority||Mostly intersects classic Eudora’s Set Priority To, except for the omission of the Raise and Lower priority settings|
|Make Label||Tag Message|
|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 classic Eudora|
|Skip Rest||Stop Filter Execution|
Eudora OSE adds the following filter actions not found in classic Eudora:
- Add Star
- Delete Message
Delete Message could be accomplished in classic Eudora 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.
