I wonder if this is due to how a cluster is configured to function internally.

Tell us more about the cluster, is it one of those ‘fancy pants’ high availability, auto backup heart beat things, or is it more a traditional multi server (master slave style) setup.

Either way you may need to disconnect the servers from one another and delete the offending files / directories either via dove or or via the os (although reading your original email it sounds like you are already attempting this).

If you have a fancy cluster this may actually be more difficult than it sounds and have interesting (unwanted) side effects, also the underlying database (if you are storing emails that way) may have a method to remove data

I assume you are keeping back up copies of all those emails somewhere, just in case you need them in the future.

See this wiki article to better understand what I mean by the ‘fancy pants’ clusters : https://en.m.wikipedia.org/wiki/High-availability_cluster https://en.m.wikipedia.org/wiki/High-availability_clusterThey sound very cool, but I suspect are overkill for a mail server, unless your database is already inside one then it would make sense I guess.

Hello,

I just use the cluster/replication functionality integrated into dovecot, nothing more. There is no database involved. I use LDAP for the authentication. The mails are stored locally on each server and replicated with the replication feature of dovecot.

I followed this wiki article: https://wiki.dovecot.org/Replication https://wiki.dovecot.org/Replication

Hello,

So nobody use the replication feature? or nobody never ever remove a mailbox? or maybe my question is so dumb and I should RTFM something? :)

Do you need more information to help me to debug that issue?

Thanks.

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).
