What mailbox format is being used during the failures, maildir or mbox? Might make a difference. (I've always thought maildir is safer than mbox, because one maildir file gets corrupted and one message is lost, while one mbox bit gets flipped and all the messages are lost.)

That's a good pont. I use maildir just for that reason. But maildir manages flags via filenames, so it might be a filename gone wild (as Michael said in the other mail).

The questions then are, must the filenames contain only ASCII characters, and if so, is there a tool to scan for such non-conforming filenames?

In theory the characterset and filename format used by maildir is well defined, e.g.: 1619077924.27553.FnAjk:2,RS 1624538432.5263.6czTL:2,S
where the part till ":" is the mails uniq id, "2" is the version (there are rumours of a "1"), and flags (P)assed, (R)eplied, (S)een, (T)rashed, (D)raft. I think dovecot uses 26 char fixed lenght names and small chars for not set flags - IMO that's why dovecot and kmail cannot use the same directory tree.
So question is what goes wrong with the indices? IMO these are special to kmail. I think they got introduced ages ago to speed up the scanning of the directory tree.

Hey Nik (or anyone else), do you know where I can dig up the spec's for maildir's characterset requirements (or actually TDE's KMail implementation of such would be better)?
Best, Michael

Well that's convoluted! Nor does it indicate what it considers as a valid characterset(s) to use to create the pid/uid. I’ll swag printable ASCII and see what shakes out from there. If it works I’ll post the script here.
Thanks!, Michael

I think you'll have to look at kmails code to get decent description. maildir of kmail ist not maildir of dovecot nor maildir of postfix or cyrus. All are close, but not identical.
