TDE 3.12 and KMail

Hello everyone, My old KMail3.10 directory contains a total of 1GB,for212internal directories. For each directory, I had to select all the e-mail content, then applied for registration under the "mbox" format, importable by other email-clients. This was because KDE4 did not offer a smooth transition from KMail3.5 (or I missed it!). Now I discover TDE and Thunderbird, I would like to return using KMail. My question is: "My KMail3.5 directory (and the 300ko kmailrc, including many filters) will be treated without difficulty by KMail3.12 or is there a risk of existence of time bombs in the bowels of KMail after this transition ? Did some Trinity-User do that ? Thank you Greg. I see two metaphors now... Good luck to everyone, Patrick # head -n 2 /linux/.../suse-home/user/.kde/share/config/kmailrc [$Version] update_info=kmail.upd:1,kmail.upd:4,kmail.upd:5,kmail.upd:6,kmail.upd:7,kmail.upd:8,kmail.upd:9,kmail.upd:3.1-update-identities,kmail.upd:3.1-use-identity-uoids,kmail.upd:3.1.4-dont-use-UOID-0-for-any-identity,kmail.upd:3.2-update-loop-on-goto-unread-settings,kmail.upd:3.2-misc,kmail.upd:3.2-moves,kmail.upd:3.3-use-ID-for-accounts,kmail.upd:3.3-move-identities-to-own-file,kmail.upd:3.3-aegypten-kpgprc-to-kmailrc,kmail.upd:3.3-misc,kmail.upd:3.3b1-misc,kmail.upd:3.4,kmail.upd:3.4a,kmail.upd:3.4b,kmail.upd:3.4.1,kmail.upd:3.5-filter-icons,kmail.upd:3.5.4,kmail.upd:3.5.7-imap-flag-migration-2,kmail.upd:3.1-new-mail-notification
