I do not know what you are talking about, but I recall you mentioned before
you had issues with your mailbox/es.

AFAIR you are using local MailDir with tons of mail

I recall experiencing similar with KDE3 like 12y ago. Unpleasant situation
for sure!

I don't know exactly, but I know what solved my problems was to setup imap
server between the directory structure and the client. The server where the
mails are is 4cores/32GB mem, however the server is not very fast - I am
not sure why - I suspect the disks are not the fastest, but I do not
experience any issue with mails.

Few years ago I integrated  dbmail for a customer. It is extremely fast.
Think about migrating those tons of mails.

I know it is not exactly an answer, but I can not think of any other. As for
kmail I have not looked into it in detail, but it is complex - one has to
be able to reproduce the problem to help you find a solution.

Also are you sure nothing else is using your local Maildir? I know you have
many scripts for this and that.
