You can define a purge rule for every folder. Also a rule to move it to archive.

I want to shrink by purging the older emails previous deleted manually. I has the Auto-Purge setting.

I suppose that I can not do it configuring "Default message expire policy for private mailboxes". Or can I? I suppose that is to delete and purge active messages.

Seldom times appear notifications of purged messages at Aide and if so only one purged message or EEDI (??)

Are there some way to shrink the size of the main citadel data file without compromizing the citadel stability?

Do you have the auto-purger configured to delete "old" messages?

You can do this at the site-wide level, or on an individual room (such as your trash folder).

If new data is arriving at approximately the same rate old data is expiring, then yes, eventually you will reach an equilibrium where the database files stabilize in size.

Do look in the Aide room for messages confirming this.  The helpful Citadel Aide will tell you how many objects are being deleted during the nightly purger run.

That's really neat.  The current implementation of Citadel was specifically designed so that it can run as a self-sufficient standalone service or be part of a larger software ecosystem.  I'm thrilled to see that you're doing the latter.  

I'm curious how you've coupled Postfix and Citadel.  Are you using the LMTP socket?

At the moment I'm actually not using LMTP between Postfix and Citadel.

The current setup uses Postfix mainly as SMTP frontend together with the traditional virtual/local transport model while Citadel remains the central communication and storage platform behind it.

I intentionally kept the architecture relatively classic and modular instead of tightly coupling everything together.

 

The overall goal was long-term maintainability, transparency and low operational complexity while still implementing modern mail security standards around the platform.

At the moment I'm actually using Postfix as SMTP frontend together with Rspamd, and then forwarding internally to Citadel via SMTP on port 2025.

So the current architecture is roughly:

Internet -> Postfix -> Rspamd -> Citadel SMTP

I intentionally kept the setup modular and relatively classic Unix-oriented instead of tightly coupling everything together.

 

LMTP is something I'm currently evaluating, but the existing SMTP-based integration has been extremely stable and easy to maintain so far.

Migrated my Citadel setup from internal SMTP delivery to native LMTP

Hi everyone,

after running Citadel in production together with Postfix and Rspamd for quite some time, I recently migrated the internal mail delivery path from SMTP (localhost:2025) to native LMTP using Citadel's Unix domain sockets.

The setup is running stable in production now and works very well.

Current architecture:

Internet | Postfix | Rspamd | LMTP Unix Socket | Citadel 

The migration uses:

  • Postfix as SMTP edge gateway

  • Rspamd for filtering and signing

  • Citadel as backend groupware and mail store

  • LMTP over Unix sockets for local delivery

I documented the migration process, configuration changes and testing steps here:

Postfix LMTP Migration Documentation

The repository itself is here:

modern-citadel-mail-platform

Maybe this helps someone building a modern Citadel-based mail platform with Postfix and Rspamd.

 

And thanks to the Citadel developers for still keeping classic Unix-style groupware alive 🙂

I have a personal Citadel email server with 2 users. I again state, a user must have Admin rights to configure the "Message expire policy". Can I give Admin rights to a user and configure the "Message expire policy" and then revoke those rights and the settings will remain? 

Or could that be changed in future releases?
