### Description of my issue

Greetings,

My SMTP certificate expired on January 23. As a result, I’m not able to send mail using K9 or Thunderbird. There is no indication in the webmin or diagnostics that anything is wrong, and I can’t find any way to renew the certificate in the webmin or yunohost command suite.

How do I address this? I can, of course, manually create a new cert and adjust postfix settings but yuno in general doesn’t like when I do things like that.

Ah yup, it was. Thanks @Benance.

To prevent the clickthrough:

- Regenerate the postfix conf:

```auto
sudo yunohost tools regen-conf postfix

```

Or:

- Update to 11.1, in which it is apparently fixed

Cheers!
