So ... all the weird issues you've been having were just constrained system resources? It's interesting, because Citadel isn't very resource hungry.
But this tells us perhaps that we would be well served by detecting that kind of situation and saying something about it.

We already refuse to accept new messages when there is less than 100 MB free on the disk. Perhaps we need to look at memory too.

I forgot.

Dear All,

Until now when I sent an email with a new email address that email address was registed in the "Contacts" folder.

It is not happening anymore. I suppose that is happening since last Centos 9 update (with glibc (??) update, one of the Citadel dependencies was updated).

Notice that Thunderbird had also a recent update.

Is it happening with someone else?

Thank you,

Luís Gonçalves. 

I made a dump and a load of the database and it start working but I do not have certain about if it is the reason.

Now a question. The contacts not being updated with new email addresses, is it meaning that the emails were not sent?

For information, the emails appeared in the "Sent Itens".

After installing Citadel no DKIM was generated.

Is there a way for me to install  a public and private DKIM key in Citadel sever

After installing Citadel no DKIM was generated.

Again, there is no way to install a user-generated DKIM key into Citadel.  Citadel generates the private key for each domain and stores it in the database.  When it does so, the corresponding public key is posted to the "Aide" room.

If you are missing your key, you can delete and re-create your local domains on this screen:

[ Administration --> Domain Names and Internet Mail Configuration --> Local host aliases ]

When you do so, new DKIM keys will be generated and posted, and you can use those.

Ok, so I just ran a quick test and confirmed: you can add a bogus domain (example.xxx or whatever) and then go right ahead and delete it, and it'll post the keys for all of your existing domains as well.

I have deleted the domain and a new DKIM record was generated but  using easydmarc  to test it gives the following result:-

We couldn't find a DKIM record associated with your domain. You need to generate DKIM record to protect your domain against email phishing attacks.

easydmarc appears to be a scam site that wants to sell you a service, and deliberately shits on your domain to make you buy it.

Instead, try https://dkimvalidator.com

No signup.  It gives you an address to which you send an email.  You send that address an email, then go back to the site and it tells you if that message was properly DKIM signed.

Many thanks can now send emails to google accounts without rejection

Thanks again

Hello,

I'm trying to install Citadel on my Rpi3 using your easyinstall script. The script does not complete. During installation it needs a certain Berkeley database file. This download is extremely slow and/or the file cannot be downloaded. When I go to https://easyinstall.citadel.org/db-18.1.40.tar.gz myself using a browser the download also fails.

Any help is appreciated.

Regards Bart

A piece of the script output is:
