I see same symptoms when opening a mail in thunderbird 2 or 3 weeks after I received it, without moving it in another folder. But using "repair folder" in TB, I get it back, so for me it looks more like a TB cache problem.
I've still not managed to solve for this problem; 'repair' doesn't fix it.
Anyone here have a reliable fix -- either on the TBird &/or Dovecot sides -- to get these subfoldered attachments openable/readable? Ideally without the need for manual intervention each time?
with Tbird cache(s) DISabled,
browser.cache.disk.enable = false
browser.cache.memory.enable = false
browser.cache.offline.enable = falsethis issue continues.
That suggests that this is NOT a TBird cache issue?
Reading,
https://doc.dovecot.org/configuration_manual/mail_cache_settings/
https://doc.dovecot.org/settings/core/#core_setting-mail_cache_fieldsI suspect these params in Dovecot
mail_cache_fields =
mail_always_cache_fields =
mail_never_cache_fields =
mail_cache_unaccessed_field_drop =, which atm for my install are @default values, may need to be modified.
if so? to what?
