Hello team Please could you help me, 1 month ago I installed carbonio ce in a small company, everything was working correctly. Yesterday the carbonio ce server was restarted, but when I start again it is not possible to send messages, the error it generates is:

Hi @almarulanda,

Would it be possible to upgrade to the latest version

apt update && upgrade

and see if it resolves the issue and let me know? I couldn't reproduce your issue. If you have been able to solve the problem, please let me know what you did to resolve it.

Thank you very much.

Hi all:

Thanks for your comments

Hi,

Sorry to hear that you are facing issues.

Could you please try this and let us know if it works for you or not:

zmprov ms mail.example.com zimbraSmtpPort 25

It's a workaround. But it also suggests that some went wrong during the installation process.

Therefore, we would strongly request and recommend you follow this forum post to perform a clean installation.

Please let us know your feedback.

Thank you so much for being with us.

Thanks and regards,

Hi,

That is a workaround for another issue.

It's a workaround. But it also suggests that some went wrong during the installation process.

Therefore, we would strongly request and recommend you follow this forum post to perform a clean installation.

But as I mentioned, I think it would be better to install a clean version following either our official documentation or this post.

Thanks and regards,
