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).

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.

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!,

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.
