Hallo Francis,

have you tried removing the account from your ldap? If dovecot has no information about a particular user, it won't replicate.

Then you would have to delete the mailbox (on both cluster nodes) from the filesystem (rm -rf /path/to/mailbox)
During testing you could move the mailbox somewhere else instead of deleting it, just in case something does not work as expected.

Deleting files on another server could be automated with ssh (ssh keys).

I'm also using single instance storage for attachments. Because of that, I think I can't just remove the mdbox storage with rm because I'll be stuck with attachments from removed mailboxes. Am I wrong?

you may be right. I don't know if any tools like doveadm deduplicate will check for orphans.

On a new server you could disable sis and use a filesystem with deduplication instead (e.g. vdo)

This is why I first use doveadm flags/expunge to mark as removed all messages then I use doveadm purge to remove them from storage. I can't use theses commands on deleted/disabled user, I get an error saying the user cannot be found, so I can't remove them from LDAP first.
