Re: SMTP error 454

Your maillog contains many messages about being unable to allocate memory, did you already restart the server?

Also, I see in the same log that you have certificate issues which might be the probable cause for error 454.

I restarted the server and the problem persists. What could I do about my certificates? Here's some config files just in case. Thanks.

PS: These certificates were generated automatically by another program a few days ago. I didn't generate them for iRedMail particuarly, but since when I was going to certbot said they were the same, I just used the old ones:

"You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry."

Re: SMTP error 454

Did you follow all the steps in https://docs.iredmail.org/letsencrypt.html ?

Did it fail directly after changing the certificate? If so, I think you need to re-check everything you did.

I see the certificate is created February 8th (yesterday) and is a valid certificate when I connect to your servers' webpage. This means that NGINX works and the certificate itself should be correct.

PS. I see that you changed the paths to the certificate files in main.cf and dovecot.conf files, that is different from the advised steps. The advise is to use symbolic links so that the files don't have to change and you will stay with the default setup. Not that it can't work that way but is more prone to errors because you have to change more files.
