I see this periodically as well:

"user_ops: 0 not found"

 

Thoughts?

It's a harmless side effect, you may safely disregard it.

I keep failing on install at 96%.  Installing on Ubuntu 16.04.  Anyone seen this?

Actually it is after install and during setup.   I get through setup and it says Restarting Citadel server to apply changes and gets to 96% and never moves.  Not sure what to do.

You might try just starting up Citadel server manually and logging in.

Hi guys,
We use the Citadel in our company.
There are ~50 users on the server, the mail traffic is quite heavy because of large messages with attachments.
The size of Citadel partition is 180Gb, and we are running out of space on this partition.
We started cleaning process when there were about 8Gb of free space (4-5 weeks ago).
I am pretty sure a lot of space should be free at the moment, we have deleted all unused accounts and cleaned all other account. In fact, there wee lots of Sent item folders with >15000 messages and now all of them have been cleaned.
The empty space is still decreasing, the process is quite stable. Now we have less than 3Gb left.
We have added all the available server free space to Citadel LVM partition, so no more options to get free space are left.
And I am pretty sure there has to be a lot of free space in the internal Citadel database.
I am pretty sure that real life process is not as it described in FAQ section Why doesn't deleting messages free up disk space: "When messages or other data are removed from the store, that spaceis made available for other data".

We run Centos 6 and the last Citadel v.8.24 from the repository.


Please, advise.

Thanks!

Citadel (that version) doesn't free space of deleted mails. It marks the
mail as deleted then re-use that space when is needed.

I got the same issue some months ago. How I mitigate this problem:

I need to give aide level access to each user account.
As that user, using webcit I open it's mail room.
Go to Advanced "https (server) /do_template?template=display_main_menu"
Then "Advanced room commands"
- "Edit or delete this room"
- "Message expire policy"
There are two:
"Message expire policy for this room. Mail"
"Message expire policy for this floor. My Folders"
Check the documentation for this options.
**Don't forget to rollback the AIDE permission on the users accounts.**

- - - - -
It's sad but this issues is with this old versions.

I recall that IG was working in an auto-shrink for the database for the
new versions. I don't know is this is available now in the current version.

In 2017.Apr.25 the space used was:
71847571456 Apr 25 11:53 /var/lib/citadel/data/cdb.08

In 2017.May.18
71847571456 May 18 11:19 /var/lib/citadel/data/cdb.08

And today:
71847571456 Aug 10 14:40 /var/lib/citadel/data/cdb.08

See? the space is not growing; is reusing the space of deleted old mails.


Regards.

I started a reply to this a few days ago, but it sounded mean.  Still don't know any other way to say it. Take in spirit given, to try and help you.

First thing is, get some more drive into that box. If you have a company of 50, someone should have the ching for an SSD, a node, or whatever your need.  2nd thing is, why would you not believe the FAQ? You should. Like any other dangerous spinning impliment you should respect BDB, if for no other reason than that you don't fully understand it.  3rd, bring up a redundant box, and do a fresh ez-install, so you can pull messages over IMAP as a precaution. That's an entry-level admin responsibility, particularly in a time of uncertainty. 

You can be the Wizard, or the guy who trashed the mail.  Treat the situation wholistically.  Your role is to maintain working mail service, not so much to discern inner workings of mysterious data store. That autopsy can be done later. So.. Create backup system, add drive space, locate your testicles, reduce the message size, restart. Announce new policies. Backup system is backup. Keep the emails flowing.  Tell them they can send pictures of the pool party through gmail. When you eventually understand the huge piles of meaningless crap they send to each other, you'll fully understand the wisdom of this. 

Good luck. 

PS.  My experience is that cranking up Maximum Message Length to ridiculous sizes tends to cause instability on all mail servers.  Nobody wants to hear this, but sysadmin has to have enough balls to enforce a policy one in a while, lest you find yourself a slave to the unrealistic expectations and unrestrained passions of the Barbarian hordes.  This is not unique to Citadel.

Subject: How to Crash An Email Server With A Single Email

[Reply] [ReplyQuoted] [Headers] [Print]

5 of the popular mail parsers for Node are susceptible to Denial of Service attacks by sending one email with 1,000 empty file attachments via event loop.

https://snyk.io/blog/how-to-crash-an-email-server-with-a-single-email/

The author has some good advice:

Along the way, I learned that some policy decisions might be better made in the email parser, rather than in the email server, and vice-versa. This included policy decisions such as rejecting obviously malicious, corrupted or truncated Base64, Quoted-Printable or character encodings, rejecting duplicates of critical headers, limiting the number of multiparts, and limiting backtracking due to false positive multipart boundaries.

Earlier this year, I got in touch with Jamie Davis, who wrote an excellent guide to not blocking the Node.js event loop. Jamie was actually doing research on event loop attacks and I suggested that some email parsers out there might be vulnerable to a multipart attack. I was surprised to see the hypothesis confirmed in every Node.js email parser I tested.

Anybody want to get together and do some citadel testing along these lines?  There might be some cases which affect us.

I hate to be the bearer of bad news here, but there's very little that the Citadel team can do to support the version that was packaged with your operating system.  We've been known to provide same-day bug fixes if you are using our build, but unfortunately 8.24 is years old.  As was mentioned, we've done a lot of work in the area of database maintenance and storage management, but we don't have a way of getting that work to benefit you if you have such an old version.

We started cleaning process when there were about 8Gb of free space (4-5 weeks ago).

The configuration setting "c_shrink_db_files" if set to 1, will cause Berkeley DB to compact your database files, keeping on disk only the space that is actually needed.

However, as previously mentioned, you need to be running a newer version of Citadel.  This option appeared in Citadel version 913, which was released in November 2017.

Mon Jul 30 2018 04:06:48 PM EDT from Zoaky @ Uncensored Subject: Citadel on Raspberry Pi

Hello

Has anybody managed to get a fully working install of Citadel on a Raspberry Pi 3+ running Rasbian Stretch? I can get as far as logging in, setting up accounts etc and adding domains in the Domain names and Internet mail configuration section. but there seems to be no way of selecting a preferred email address. The field is blank.

The install is quite messy:

  1. Update the Pi's OS
  2. sudo apt-get install citadel-suite (which fails due to configuration setting c_default_cal_zone is empty, but must not - check your config! error msg)
  3. Enter sudo sendcommand conf listval
  4. Enter sudo sendcommand "CONF PUTVAL|c_default_cal_zone|Europe/London" (in my case)
  5. Reboot
  6. Login
  7. Tried re-running setup again and it just hangs
  8. Reboot
  9. Login
  10. Enter sudo apt-get install build-essential curl g++ gettext shared-mime-info libssl-dev zlib1g-dev
  11. sudo -i
  12. cd /opt
  13. Then run Easy Install the normal way: curl http://easyinstall.citadel.org/install | bash
  14. Setup will complete and ask you to configure the server settings
  15. Login via the web interface


That's as far as I can get

I know this is far from ideal but its the only way I've found

Anybody got any ideas?

P.S apologies if I've managed to post this twice

Easy Install will now attempt to install the prerequisites for you, if you are running on a Debian-like or RedHat-like operating system. You didn't mention what operating system is running on your Pi. If it is Raspbian, you should be able to follow the instructions for Easy Install on Debian and it will run out-of-the-box.

You mean you can't set the mail addresses under advance -> Update your contact information -> Primary Internet e-mail address and Internet e-mail aliases

I had this problem too, I can't exactly reproduce what i did,

but it has to do with the user configuration (your login).

So edit your account probably with admin rights. You can enter 2 Mailaddresses in the fields 

Than save, logout and login again. Then try to enter the mail addresses in advance -> Update your contact information -> Primary Internet e-mail address and Internet e-mail aliases

Please tell if that was the reason....

I want to have a sensible, considered discussion about this, please don't just ignore me in the hope I'll go away.

I want a mail-server package, that and nothing more. I've tried iRedMail and James and Citadel, Citadel was by far the easiest to get going because it has a .deb in the Ubuntu repository (v917), but it has all these bells and whistles that I don't want, not for space reasons, but for simplicity and ease of maintenance.  I just want a POP3S and SMTPS server, and a simple administration settings/monitoring web page with admin login.  If everyone ran their own mail-server then Google/Yahoo/Micro$oft might go out of business.

I have downloaded the sources, and can't understand it. There doesn't seem to be any structure to it, probably due to its long and varied history.

Would it be a lot of work for someone who already knows the code to extract just the bits I want?  Has anyone ever tried this before?
