Subject: Re: File size restriction
From https://en.wikipedia.org/wiki/Email_attachment
Also note that all these size limits are based, not on the original file size, but the MIME-encoded copy. The common Base64 encoding adds about 37% to the original file size, meaning that an original 20MB file could exceed a 25MB file attachment limit.[13] A 10MB email size limit would require that the size of the attachment files is actually limited to about 7MB.
Hi,
I was wondering if there was a file size restriction on incoming mail via citadel? reason I ask - a client sent me 11mb PDF document.. I failed to receive the attachment.. only the email appeared with no attachment.. after multiple tries I asked him to sent to gmail.. I received the file correctly.
please help.

Subject: citadel in docker container >> configuration issues
Hi, I'm trying to install a citadel/webcit server in a container (docker.-ce), but I'm finding it difficult to set up, for the smart-host on topic.
1) Oracle's mail delivery service (OCI) does not accept me.
2) I can't find where the Citadel configuration files are in the container (I would like to try setting the file manually).
Can anyone give me a hand?
Thanks!
Hello,
i'm running citadel as my own Mailserver at home.
From my IPCAM's i send Emails with a JPG to my internal email address on my citadel server.
In paralell i send it also to my google address to see is it send correct.
In my google email address i can see the attached jpg but not in citadel.
On the email overview i can see that an attachment is available, but if i open the mail no JPG or attachment is available.
If i receive an Email vrom outside , which is collect via fetchmail, attachments are visible.
There ia also a roundcube webfrontend connected to the citadel, but also there is the JPG not visible.
How can i find the right configuration to see the JPG from my IPCAM ?
Best regards
Alex
Subject: Re: No JPG attachments on Email from my IPCAM
OK it looks like that this is an embeded JPG in the mail.
Is there a way to switch between Text and HTML view ?
Best regards

To identify a mail delivery problem, we will need to know what you tried, what was the expected result when you send mail, and what the actual result was (error message, delivery status notification, different behavior than expected, etc).
Regarding the containerized Citadel service: there are no relevant configuration files inside the container. If you are able to log in to Citadel as an administrator, all serviceable configuration items are reachable from within the application.
Installed docker.io on OrangePi 5 Plus running debian. Followed the instructions to get a "permanent" running citadel instance. What is the default admin login for the container or is it the first user created?
Found it - admin/citadel. Changed for my installation. thanks
I tried the easy install because I have always loved Citadel but when it's compiling, I end up getting an error for an undefined reference to libiconv and libiconv-close in libcitadel. Anyone else have this problem?

This is impossible to answer without knowing the operating system you are attempting to use.
Is it Linux or BSD? What distribution? What version? What was the error message you received?
If you're on a Linux system you really should just use the containerized version; it's much easier.
Subject: Citadel Easy Install crashes with segmentation fault
Hi,
I am running a fully patched release of raspian bullseye on a raspberry pi. Installing Citadel using the Easy Install method.
Having done all the compiles and answered all the configuration questions, Citadel restarts then issues the following message:
Restarting Citadel server to apply changes
bash: line 643: 26257 Segmentation fault /usr/local/citadel/setup < /dev/tty > /dev/tty 2> /dev/tty
Citadel Easy Install is aborting.
The last few lines above this message may indicate what went wrong.

But it might be easier to just run the container version of Citadel, it's guaranteed to work.
Subject: First the Cisco firewall lost the NAT address to Citadel
Here is a good one....
Last Wednesday, just as end of day, the Cisco ASA firewall went down on the NAT for Citadel..... version 972
While there are automated backups running everyday, everything continued to work..... the backup MX took over spooling email traffic, and the Citadel continued perating within the environment, no mail was flowing due to the disconnected NAT.
On Friday, the IP of the OUTSIDE Citadel got listed at Spamhaus ZEN.
Then the later Friday, the AD LDAP connection failed.
Backups continued, however, the database was encountering problems which was corruption.
Monday morning, client called NO emails.
Found the AD down, and was unable to connect to AD server. Citadel was unresponsive. ran sysemctl stop on Citadel apps (incl webcit) and restarted. AD restored.
Found the firewall was not NATted. Reset the the firewall (full power reset as ASA wasnt reachable)
Mail started to flow, but AD failed again causing 551 user unknown, emails rejected.
De-spooled MX backup server sent emails which were rejected (3.5GB)
Mail from Friday to Monday lost.
Got Citadel up again with AD, but seems the database was corrupted. Ran db_recovery, no joy. Ran database_cleanup, mail outbound worked, inbound appeared to work as headers came through, but no body. Attempted to restore from backups going back each day from Monday. Several cdb failed db_verify.
So all the way back to Wednesday were restored. All clients were were backed up to PST files. And tried to update to 996. System easyinstall ran fine.....until the setup portion of the install where it hung. No activity for several hours and no joy.
Im restoring the backup of the 972 as I cant wait to figure out where issues are as I must create new cdb and load all the PSTs to return ops.
I cant figure out where it went wrong.....
Well,
A number of users are attempting to clean their email accounts of Deleted Messages and Trash and the citadel user "citadel" user account 1001 is seeing application crashes:
This system has been functional since last year with nary an issue. 956 was initial system. Currently at 972.
It appears that webcit-http did a core dump yesterday with an issue in libcitadel. I could provide log snippets on request. The core dumps today appear related to the imap-cleanup procedure. A number of users are clearing the Deleted Messages and Trash in their accounts as well as Main Floor Trashcan. We have had two core dumps in as many hours. A couple of users have more than 10K emails to empty....
I
Running 972 on a Redhat 9 EL
LDAP Microsoft AD on 2008R2 Forest/Domain
Aide has created 820 MILLION accounts
User Creation Notice
New user account <> has been created, from host []
Happens at various times periods, anywhere from 1 to 6 per minutes.
I suspect our friends at Microsoft as the culprit as several other Citadel server dont exhibit this behavior. There are several AD authentication schemas but not at the version with the spurious account creations
Anyone see this before.
And yes the plan is to go to 996 as rapidly as possible........
Cheers
I'd like to hear more about how you're using Citadel with AD because that's definitely a supported configuration but I don't run it in production, so if there are things we need to adjust to make it easier day to day, we can work on that.
I can send some logs and configs from the misbehaving system.
I also would like to maillog to show the local recipient. Is there a way to expand the level of the logging to show this?
Subject: Re: Follow up on massive account creations

Yes. Citadel Server sends logs at all logging levels, including "debug" (the highest). Adjust your syslog configuration to capture log messages from citserver at the debug level and you will definitely see alias expansions.
