More on Eudora vs. Apple Mail

A reader emailed me (probably using a state of the art email application like ELM) the following list of more reasons to pine for the lost power of Eudora:

I did the same thing recently, but I'm thinking of switching back to Eudora for
various reasons, in no particular order:

1. Different mail check intervals for different accounts
2. The pesky problem of mail getting marked as read when the preview
pane is open and you've selected that message for no good reason.
3. Better threading in Eudora -- sometimes hitting reply to reply to
a message takes a very long time, or have you ever tried to interrupt
a message being sent but blocked over a certain port? There's more
feedback while sending and receiving mail, too.
4. You can really queue mail instead of sending it as soon as you're
done writing it
5. Option-clicking to select similar messages by sender, subject, etc.
6. Type to select messages in a mailbox
7. Filters that work on outgoing as well as incoming messages; the
ability to have filters work only manually, instead of automatically
8. Real email nicknames
9. Doesn't use the OS X address book -- this is actually an advntage,
as I can have big groups of email addresses that I wouldn't want to
see in my OS X address book
10. Multi-criteria email searches
11. I have a lot of mailboxes, but I don't necessarily want to see
them all in a list. Mail.app forces me to see all of them or else put
them in folders where they're less accessible. Eudora's toolbar
allows me to make just the folders I like accessible, and hide the
others.

As far as the Mail junk filter is concerned, why don't you use
SpamSieve? I've used it with Eudora and Mail. No conversion hassles.
Much better than anyone else's spam filter!

I will check out SpamSieve. Maybe try Thunderbird too...or at least research it.
