Hi Jörg, This sounds a little bit like this Thunderbird issue:
https://bugzilla.mozilla.org/show_bug.cgi?id=1708981 Two Cyrus bugs were found while it was being investigated, which were fixed by: https://github.com/cyrusimap/cyrus-imapd/pull/3605 https://github.com/cyrusimap/cyrus-imapd/pull/3606 https://github.com/cyrusimap/cyrus-imapd/pull/3664 These fixes are in Cyrus 3.2.9 and 3.4.3, and the 3.6 betas. The fixes are not present in 3.0, because the code has changed too much since then for the patches to apply. The bugs probably are though. I don't know what (if anything) changed from the Thunderbird side, I didn't follow that part of the discussion. Perhaps Thunderbird now expects the server-side problems to be fixed, and doesn't compensate. If you wanted to upgrade Cyrus while staying within apt, it looks like buster-backports has 3.2.6-2~bpo10+1... though note that 3.2.6 is three releases older than 3.2.9, so it won't have these fixes either unless the deb maintainer has included them as patches.
