279880 - IMAP email content is not locally cached

Status: RESOLVED EXPIRED

(Thunderbird :: General, defect)

Description

[Emmanuel Blot]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Email content retrieved from a remote IMAP server is not cached on the local disk.

This leads to download the very same email as many times as it is read by the user.

With low bandwidth connections, or slow IMAP server, it is very painful to read
large emails (emails with large attached files).

Reproducible: Always

Steps to Reproduce:
"Offline" setting (on or off) on the INBOX folder does not change the behaviour
(as long as the email is not explicitly downloaded for off line reading)
Actual Results:  
The same attachments are downloaded again and again, everytime the user moves
back and forth from one email to another

Expected Results:  
Once a IMAP email has been retrieved from the server, Thunderbird should keep a
local copy of the email, so that it minimizes the server load, the connection
bandwitdh usage and overall, the time spent waiting to retrieve data that have
been already retrieved.


All releases of TB show this issue (up to 1.0 final at least)

This limitation shows up with both 'embedded' attachments (such as a JPEG file,
diplayed within the email body) and 'regular' attachments (for which the 'open
or save' popup is displayed)

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.

This is actually INVALID. Thunderbird caches emails offline, as long as you ask
it to. File | Offline | Download/Sync Now... | Select..., and check all the
checkboxes.

This is a DUPE of 337380 and 354044.  This is NOT however, invalid.  This problem exists today (1.5.0.7).

Matt, do you still see a problem if using version 3?  If so, then do you agree it's s dupe of bug 345832?
