I've read through many of the knowledge-base articles on IMAP and I'm still unclear. (I've been POPing email forever.) I'm fairly new to thunderbird (switched from Eudora).

It looks like when using IMAP emails are *not* saved/stored on your computer. Is that correct?

I'd like to be able to synchronize email that is downloaded to my computer with what is on the server -- keeping mail on the server so I can sync/download with 2 other computers. It's *really* important to me that email is SAVED to my computer (and not rely totally on the server to save/store emails).

Is there an article that shows (step by step) how IMAP works? How I can make sure I have securely saved emails on my PC (not just on the server)?

Thanks for any help/direction.

What version of Thunderbird? If you are using a 3.1.x version messages from the IMAP account ARE downloaded to files on the local computer if Thunderbird is set to do that under Tools->Account Settings->Synchronization & Storage. Note though that deleting messages from the Inbox (or other folder) will result in that message being deleted from the locally stored synchronization file.

To do what you describe, you can set up filters in Thunderbird to copy all messages from the folders of your choice to folders under the Local Folders "account" in Thunderbird. Message folders in that structure are independent of actions on the messages in the IMAP folders.

Thanks. I realized that I could set up a filter that COPIED the IMAP emails into a particular Local Folders folder - which I know creates duplicates, but at least I wouldn't have to worry about accidentally deleting one in the IMAP (which would delete from the server, too).

In my work, it's required that all emails are saved (aside from spam) - so it's vital that I have local/on-pc stored emails.

Thanks for your suggestion.

Dan (or others),

It has been a year since i originally posted this question.

I've run into another problem with copying emails from IMAP to local folders. The person's email is through AOL (gack). It seems like every time she opens email in the IMAP account, it creates multiple copies in the local folders. (The filter must be seeing the emails as new when she opens the IMAP emails each time or something.)

I have the filter set up to run when checking mail and is set to Subject does not contain &BLA@*VV_ The action to perform is to COPY the message into a folder under Local Folders.

What has ended up happening is that the Local Folders folder exceeded 4GB because of all the duplicates and has frozen all of THunderbird.

Is there a way to have the filter ONLY filter the IMAP email once and only put ONE copy in the local folder?

Is the user regularly compacting the IMAP message folders? Are all messages in the Inbox folder properly marked as Read and Unread?

Yes, regularly compacting. "Properly" marked as read and Unread? She reads them and they are marked as read. I don't think she re-selects/ remarks them as unread at any point.

Try deleting that filter and recreating it.

howdy y'all,

the OP didn't mention if the msgs were being merely read or composed. if they are being replied/forwarded or otherwise composed, then i suppose it's _possible_ that autosaves to the IMAP drafts folder are the source of the glitch.

you can test if autosave is part of the problem really quickly by temporarily disabling the function here ...
- tools/options/composition/general
- [] auto save every [##] minutes

simply uncheck the autosave item and see what happens. i don't think a restart of tbird is needed, but it won't hurt.

if it turns out that autosave is the culprit, you can configure that account to use a folder in your local folders account instead of the one in your IMAP account. i did that some time ago for a different reason having to do with odd timeouts on my inet connection causing tbird to leave a bazillion saves in the draft folder.

take care,
lee

@Lee -- some message have simply been read-only, some have remained unread, and some are replied to or forwarded. In each case, multiple copies are being moved into the filtered folder AND slowing down everything. (I've turned off indexing, but it still seems to be indexing anyway.)

I'll test out the autosave piece and see if that makes a difference. I may set up the autosave to go to local folders anyway, since that may help eliviate some of the sluggishness with sync'ing.

Thanks.
