Merging two sets of mailboxes

[Pedro]

Still using Eudora for email (as a client to handle Yahoo and others) via POP3. And it is the POP3 bit that is causing the headache. (I realise that selecting IMAP would leave all mail on the service-provider's server, but the sheer volume involved wouldn't be funny.)

When I go on long trip I take a laptop, and Eudora on that has its own IN and OUT mailboxes of course. When I return, integrating that history into the desktop system causes problems with date-stamps AND with the messages in a couple of other ways.

I have tried copying renamed versions of the road MB's as (1IN and 1OUT, including the TOC's) to the desktop box, and then migrating their messages into IN.MBX and OUT.MBX. But that's what stuffs it up. (All NON-I/O MB's create no issue).

Is there a "proper" way to integrate the two sets of I/O MB's?

For IN:
Set the laptop configuration to "Leave Mail On Server" (no delete
schedule). When you return, the first fetch on the desktop will pull down
all messages (they will appear as unread, but it shouldn't take much effort
to group select and toggle). This presumes the traffic isn't so heavy as to
fill the server mailbox.


However -- the main solution in my mind is to never use IN/OUT for
long-term message storage. Save received messages in dedicated mailboxes,
have sent messages filtered to (again) dedicated mailboxes -- and delete
anything left in IN/OUT...

Take into account that MBOX format is a linear list of messages
identified by a "FROM" line (not "FROM:", which is a header /in/ the
message), and typically that means time-ordered by receive (the TOC is used
by Eudora to hold message status and maybe speed up access rather than
scanning the full MBOX file for those "FROM" lines).

I've not had trouble with this. I don't do exactly what you do, but I am able to copy email from the out mailbox to another and back. The IN mailbox is no different from the others. The only difference in the OUT mailbox is that the emails have different attributes which can't be used in other mailboxes. But SENT and SENDABLE both seem to transfer to non-OUT mailboxes and back.

What problems do you see?

Thanks for the feedback. Give me a bit of time to be able to do the testing again and I'll let you know exactly, as I haven't had to do this for a while.

Oddly enough(?) the OUT box gave no surprises this time, but looking back in earlier attempts the date-stamps were all updated to the date/time of "importing" into the real OUT.MBX from the renamed copy off the other machine.

This time the IN box failed to show the "replied-to" arrow on any of the imports.

Can send you copies of the two current aggregated mailboxes if you are inclined to want to look into them.

Sure, as long as you are in no hurry. I'm a little busy at the moment buying a house with septic problems. lol A crappy situation. 8-*

Assuming that you don't want both computers to have exactly the same contents you could do something different.

I have my main computer and a laptop for travel. Eudora on the travel laptop is set to leave mail on the server.

When traveling I use my ISP's webmail interface to delete any messages that I can tell I won't want to keep, and download the mail on the laptop.

When I get home I download the mail on the main machine (which is set to delete mail from the server.

Convoluted, but it works for me

Even with "leave mail on server" I believe there is a setting to
"delete from server when deleted from trash" -- which would let you avoid
the webmail step. Just do normal download, delete the junk/empty trash, and
do another mail check so Eudora updates the LMOS stuff.

It appears to be a per-personality setting.

What happens to mail/replies SENT from the laptop?

I can't stomach the webmail interface, so I use Eudora natively on the laptop but I also leave-mail-on-server as you do. The mail sent from the laptop becomes orphaned and thus requires the subsequent catchup merging.

Would sending yourself a BCC or CC and moving your copy to a sent messages work?

They don't show up as OUT mail and are not searchable as that.

Keeping a lot of messages in OUT is not recommended anyway.
IN/OUT/JUNK/TRASH are boxes Eudora keeps status in memory, and can be
corrupted by crashes.

All my "OUT" mail gets filtered to a separate "processed mail" box as
it gets sent. The OUT box, thereby, only contains messages that are queued
to be delivered or are in draft state.

It sounds as if you may have very large mailboxes. Eudora has problems when the system mailboxes (in/out/junk/trash) get too large. There isn't a problem with user created mailboxes.

I filter all of my incoming messages. Anything that isn't caught and sent to a created mailbox is sent to a "new" mailbox. I also created "sent" and "delete" mailboxes.

I have a filter set up to put sent messages in "sent".

When I want to get rid of a message I drag it to the "delete" mailbox. Every few weeks I'll delete older messages in it (which sends them to Trash).

The Junk and Trash mailboxes are emptied and compacted when I close Eudora. This keeps the system mailboxes small. Even if the mailboxes I created are very large that doesn't cause a problem.

Even with large mailboxes Eudora will search all mailboxes, both system and user created, quickly. When you open the search window on the left you can choose one, any or all mailboxes and folders to search.

Not excessively large - IN 872K and OUT 369K. I've had them >1M on another machine without dramas. (I'm aware that Eudora loads IN and OUT at startup.) That's not the problem.
