I have lost email correspondence in thunderbird that is also not on the ISP mail server. As is usually the case, this was discovered many months later when I actually needed the emails. I am not sure how this happened: whether there was a crash of the ISP mail server, mail lost, and this then trickled down to my computer when thunderbird synced mailboxes; or, there was a crash on the local computer, the file damaged resulting in lost email, and this then propagated upstream.
Luckily I had an isync backup and could find these emails that were quite important to me. I am now looking for a good backup strategy to avoid being in a similar situation in the future. Currently I have a mbsync script that downloads /all/ emails from the ISP mailboxes but never deletes anything in the local storage. This should make it "impossible" to lose any emails. But, this makes for a very large backup since spam and regular emails that I then delete also get downloaded by this script. Right now, I run this script on an irregular basis. It was using this I could retrieve the lost emails. Perhaps I should have a second script that syncs my upstream mailbox to local storage, ie also deletes anything locally that is no longer found upstream? The drawback is that I would end up with a lot of duplicated stuff. Would be interested in hearing how other users handle the above. _______________________________________________ isync-devel mailing list isync-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/isync-devel
