K9 mail not showing all emails (google, imap)

[BenoitM-I2BC]

Hi,

I've been using K9-mail for 9years now and always been satisfied. Recently, I noticed that some emails (from my Google account illustrated here, but also from my professional account) are not displayed, even if they appear when using the webmail.

This is most probably linked to #1422, but I use a version >5.7xx in which this bug should have been fixed.

Description of the bug:

• K9mail version: 5.802
• See corresponding screenshots below: Some emails are visible using the webmail (left, bottom). For example, the Easyjet email, but this is also the case for "Google Team" message and the "Esp@ace Client" message.
• But they remains not visible in K9-mail (left, top)
• The local search (from K9 mail) does not find he Easyjet mail. The server search from K9 does find it. Once it has been found by the server search, the email does appear in the K9 mailbox (right).

I indicate:

• mails are not group into conversations
• I haven't found (yet) a pattern in the email that are not displayed (no matters when the email was sent, whether I'm or not the only recipient, ...).
• The fact that it is shown at the right place when the server search has been done suggests that K9-mail ingnore it to start with.
• I haven't seen anything obvious in the header of the email that are ignored and not sync-ed. Yet, I've posted the header of the Easyjet email below.
• I tried to recreate my mailbox from scratch (recreate a second time my gmail account): the emails that were ignored are still not fetched.

I welcome any ideas. Thanks !

Hi again. Am I the only one having this issue? Thanks

[jeroenbell]

You are not the only one 🙂 I have the same problem.

I found out that (in my case) this is because K-9 does not correctly respect the "Sync messages from" setting. It seems like it is ordering messages by id rather than date when syncing. So when you have a low "Local folder size" set (such as the default 25), it will only sync the last 25 messages with the highest id (which are not per-se the most recent ones).

Can you try setting the "Local folder size" to "all messages" to see if that solves your problem?

[BenoitM-I2BC]

Hi Jeroen. Thanks for your reply. I'm happy to hear that I'm not the only one

I haven't tried to set the "Local folder size" to "all message", but I'm sure this will indeed solve the problem, given that all messages are going to be sync-ed. Because I use K9 mail for a 3 email adresses, and storage is limited on my phone, I'd rather not sync all my messages from my 3 email adresses (but I increased the "Local folder size to 100, I'll see if it helps)

If indeed K9 is not anymore ordering by date when syncing, this is worrying. Shouldn't this be the default behavior? In 2020, I already had this issue, which then was smoothly solved by using a beta version of K9.

Seems related to https://github.com/k9mail/k-9/issues/1642

I am also having this problem, increasing the Local folder size to 100 didn't solve it. By making a server search, I managed to import some more messages but not even all of them. Any idea what is the problem? What can we do to try to solve it?

Version 6.707 still has this bug. Threads disabled. The problem folder is one that I sort messages into with a filter on the server. K-9 doesn't show any messages in the folder even though there are 800 messages in it visible with other clients. No amount of refreshing with pull-down shows them. Searching for them doesn't find them client-side, but does find them when I click on the server-side search button. But that does not make them show up in the folder as others have said, the folder is still empty.
