Dear All,

I think that is a compability problem of Citadel with Thunderbird email client.

After several steps to try to solve the problem I found that Citadel is not compatible with the last version of Thunderbird.

I tried Linux (Centos 9) and Windows Thunderbird. I tried my affiliation network and with my mobile hotspot.

I can send emails with my Android email client.

I am thinking to make a downgrade of Thunderbird. I have there all my emails from always.

But first I have to backup everything of Thunderbird. Time consuming task.

Some help is needed.

Luis Gonçalves

The problem is suddenly solved. I suppose my VPS provider was blocking the emails despite they deny. I was send bursts of benign emails. Perhaps reached some threshold of the number of emails measured by the VPS provider.
