Hi everybody,
I’m facing an issue that makes it impossible for me to put my mailcow server in production.
Here is the problem:
I tried to migrate a simple domain with 8 email addresses.
One of the mailboxes is quite big: 16Gb and more than 1000 subdirectory.
When I try to do an advanced search in the mailbox, it stops after a while with the message: “An error occurred while communicating with the mail server”.
The logs show that error: “Mailbox doesn’t exist” when the search fails (The search doesn’t fails on same directory each time) :

My mailcow installation is quite basic, I tried to increase max_heap size of solr and other memory variables in dovecot and sogo, but it doesn’t change anything.
Please let me know what kind of informations you need to help me on that problem.
