454 TLS currently unavailable Exim error| Troubleshooting Tips

 

454 TLS currently unavailable Exim errorRecently, one of our customers faced an issue where they were unable to receive emails sent to their server. Additionally, the senders would receive the following error as well:

454 TLS currently unavailable

Our technical experts had the solution for this issue right up their sleeve. Let’s take a look at the steps:

  1. First, we have to check the /var/log/exim4/mainlog file for error messages.
  2. If you see a read permission error, locate the corresponding SSL files with .crt, .pem and .key for the vesta.panel.domaintld at “/home/admin/conf/web”. Then we have to modify the permission to 664 as seen below:

    chmod 664 ssl.vesta.panel.domaintld.crt ssl.vesta.panel.domaintld.pem ssl.vesta.panel.domaintld.key

  3. Next, locate each of the domain aliases we plan to activate email at “/etc/exim4/domains”. Then modify the permission to 664.

    chmod 664 /etc/exim4/domains/ourdomain/domainaliases

After these steps, we will not have to deal with the 454 TLS currently unavailable Exim error.

However, if you are still running into the error, our experts recommend ensuring the key and cert are valid.

We can do this with the following commands:

openssl x509 -in exim.crt -nooout -text
openssl rsa -in exim.key -noout -text
