Delta Chat clients runs version : 1.14 - 1.20.2
The short story, - email server get crashed and after restoring it from backup, all email clients (Outlook, Thunderbird all phone’s email apps) started working without problem, except DC.
While we know about 3-2-1 backup rule (and actually doing 5-4-3-2-1) there happened a case where backup system missed one full day. That’s the only thing that may explain why DC clients stopped working on all clients. I tried to dig DC log and find such line:
DeltaChat: src/imap/mod.rs:800: fetch_new_messages: ignoring uid 97743, last seen was 97860
that lead me to believe that DC somehow using/counting sequence of messages and since server lost messages for one full day, DC on all devices get unsynchronized and stopped working.
DC clients successfully sending messages, but nobody can receive it.
I can see on the server, that clients get connected, moving files from
cur folder but won’t process them as DC messages.
So, my question is - what to do ?
