How large can a Eudora mailbox get before one runs into trouble? 限 that
is, before Eudora itself runs into trouble handling it?

We're talking about an essentially archival mailbox, very seldom used.

My "Dead letters"mailbox has gotten up to about 30 MB. Should I go to
the hassle of splitting it into "Dead letters 1999", "Dead letters
2000", etc? (I use the old style .toc file setting.)

For what it's worth, Eudora has the reputation of handling large mail
boxes very well; my wife's mailbox is around 20MB with 4400 messages in
it, and Eudora handles it without any trouble at all on a 663 TiBook
with 500MB of RAM, running 10.3.9. No slowing down, no corruption in six
years of use, starting in OS 9.2 through 10.2 to 10.3.9.

So do I, but I don't supppose it makes much difference.

There is a newer 6.2.4 available.

Number of items is likely to be more important than number of megabytes,
because the TOC is usually the problem -- the TOC is kept in memory for In/Out,
and had an absolute limit (32767) to the number of messages
in older versions, at least under Windows
(I don't recall when that limit was expanded, but "relase notes"
for Windows version 6.2.1.2 indicate a bug on this was fixed at that time).

I have an inbox archive of 63.4 mb (12916 messages), outbox archive of
38.9 mb and no problems. Still running os 10.4.10.

No intention of doing anything other than continuing to dump messages in
there.

According to Bill Cole, who I absolutely trust to have his facts right,
there is a hard limit of 32K messages in Eudora for Mac. The MB of mail
is less important with our modern operating systems than the number of
messages.

In Mac OS's before OS X, the size of the In, Out, and Trash mailboxes
made a noticeable difference in performance for me, and having those
mailboxes large meant I had to assign a great deal of additional memory
to Eudora, but in all the various iterations of OS X I've had no
problems.

32K messages per mailbox? Or per Mail folder?

For those using Windows versions as well, this is obsolete,
according to the Release Notes, and to Katrina Knight
(who moved from the Windows newsgroup to a "listmoms" mailing list)

"Older versions of Eudora have a limit of a bit over 32,000 messages.
Once that limit is exceeded, the toc file can't store data for
additional messages and you'll end up with the toc file getting rebuilt
every time you run Eudora and access the mailbox."

EVERYTHING YOU KNOW ABOUT MAILBOX SIZE BASED ON THAT IS IRRELEVANT IN
THIS NEWSGROUP.

Eudora 7 for Windows is a significantly different program from Eudora
6.2.4 for the Mac. It was the only major version that came out first
(and as it turned out, exclusively) for Windows. Qualcomm staff had
spoken of the mailbox message count limit on MacOS as something that 7.0
would address, but of course that never happened.

> my Trash folder is typically 35,000 to 45,000 messages (12 months'

That simply cannot work in any version of Mac Eudora. The TOC format has
a hard limit for resource fork TOC's at around 30k messages due to the
size of individual entries and a limitation in the Resource Manager on
the size of a resource and of the whole resource fork of a file. There
is also a logical limit at 32767 that applies to .toc files on the Mac.

The data size for a Mac Eudora mailbox is not so restricted. As I
understand the TOC structure, it would be fine with as much as 2GB in a
single mailbox.

YIKES!

Thank you, but I am quite fallible.

I also realized the last time I looked at this that the way the Resource
Manager works and how Eudora does TOC maintenance makes the *safe* limit
softer and more like 30k on a mailbox that is is getting changed
dynamically. Split .toc files may make it is easier to get close to the
full 32767 before running into housekeeping jams, but I don't think I'd
want to test that with mail I cared about.

MacOS X has far better and entirely different memory management than any
"classic" MacOS. One aspect of that is the dynamic allocation of memory
and disk-resident backing store for virtual memory so that apps can get
more memory as they need it at runtime, rather than having to live in a
fixed space allocated at launch time. Eudora still chews up memory, it
just doesn't make users think about it much.

Nothing major about Mac Eudora has. :)

IIRC the OP or discussion participant
had mentioned using Eudora on _both_ Win & Mac
(use of one is not mutually exclusive with the other :)

Best wishes.

I can confirm this problem from personal experience. My wife, a cat
breeder, gets hundreds of messages on a busy day from various discussion
lists she participates in, and deletes little "just in case". She has
run into this limit (latest version of Eudora, running Tiger 10.4.11,
eMac 700 MHz box). The result was that Eudora simply lost all the mail
and emptied out the In box permanently. She uses POP, so that meant she
lost everything for several months. Boy did this teach her a lesson
about archiving!

My Mac Eudora 6.2.4 shows 1/8247/101M/0 in the bottom left corner.

Is that 8,247 messages taking 101MB?

I believe so, that's how I read it.
